The hot-rolling arrangement of processing magnesium alloy plateTechnical field
The utility model relates to a kind of hot-rolling arrangement of processing magnesium alloy plate, belongs to the Metal Forming field.
Background technology
The main method of producing magnesium alloy plate at present is rolling and extrusion.With former magnesium is raw material, and rolling is produced magnesium alloy plate, pass through the side cut of alloying, ingot casting, multi-pass hot rolling and each passage, because technology is loaded down with trivial details, so complex equipments, equipment investment is high, and energy consumption height so its cost an arm and a leg, and are difficult to accepted by market.And extrusion is produced magnesium alloy plate, also will pass through alloying, ingot casting, several roads of extruding technology, and technology is also more loaded down with trivial details; Complex equipments, and equipment energy consumption is high, in addition; The magnesium alloy plate poor surface smoothness that extrusion is produced can't satisfy the requirement of products that surface aesthetic is had relatively high expectations.
The utility model content
The utility model technical problem to be solved is to provide the hot-rolling arrangement of the processing magnesium alloy plate that a kind of equipment is simple, equipment cost is low, energy consumption is low, production efficiency is high.
The technical scheme of the utility model is following: a kind of hot-rolling arrangement of processing magnesium alloy plate; Comprise smelting furnace, batcher, mould, milling train and be installed in the conveyer belt before and after the milling train; Said batcher is connected with the feeding mouth at smelting furnace top; The bottom of the sidewall of said smelting furnace is provided with discharging opening, and said mould comprises by the parallel discharging opening that is installed on smelting furnace with the bed die slide block of mold slide block, and is close to discharging opening; Leave flat channel between said mold slide block and the bed die slide block; Magnesium alloy liquation in the said smelting furnace can only flow out from the flat channel between mold slide block and the bed die slide block, the exit of the flat channel of the initiating terminal of said conveyer belt between mold slide block and bed die slide block, and the conveyer belt between said mould and the milling train is installed in the temperature control furnace; The end of said conveyer belt is installed slewing rollers and coiling machine, and the conveyer belt between said milling train and the slewing rollers is installed in the annealing furnace.
Adopt technique scheme; With this device fabrication magnesium alloy plate; Simplified technology, only needed just to have accomplished production from former magnesium to magnesium alloy plate through smelting furnace alloying smelting, mold cured distortion, temperature control furnace temperature control, mill milling distortion, annealing furnace annealing, coiling machine rolling.This complete equipment is simple, and the equipment early investment is low; Owing to need as existing rolling and extrusion process, repeated heating not saved consumption of heat energy; With this device fabrication magnesium alloy plate, yield rate is high; This equipment is fit to produce continuously, and production efficiency is high, reliable product quality.
In technique scheme; In order to save the energy: be respectively equipped with the cooling air circulation passage on said mold slide block and the bed die slide block; Be equipped with the circulation water back in the furnace wall of said annealing furnace and temperature control furnace, the exit of said cooling air circulation passage is communicated with the circulation water back of the furnace wall that is positioned at annealing furnace and temperature control furnace through the waste heat recovery pipeline.Because the temperature of the magnesium alloy liquation in the smelting furnace can reach more than 600 degree, through mould the time, the air cooling reduces its temperature, thereby solidifies.At this moment, the increase in temperature of cold air can be used for reducing the consumption of the energy to annealing furnace and temperature control furnace heating.
In technique scheme, operation for ease: said smelting furnace is installed on the smelting furnace base, and said annealing furnace and temperature control furnace are installed on the furnace base support.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, low cost of manufacture, and energy consumption is low, production efficiency is high.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Embodiment 1; As shown in Figure 1, the utility model is made up of parts such as smelting furnace 1, batcher, mould, cooling air circulation passage 5, waste heat recovery pipeline 6, temperature control furnace 7, milling train 9, the conveyer belt 8 that is installed in milling train 9 front and back, annealingfurnace 10,slewing rollers 11,coiling machine 13, furnace base support 14 and smelting furnace bases 15.Said smelting furnace 1 is installed on the smelting furnace base 15; Saidbatcher 2 is connected with the feeding mouth at smelting furnace 1 top; The bottom of the sidewall of said smelting furnace 1 is provided with discharging opening, and said mould comprisesmold slide block 4a and bed die slide block 4b, and saidmold slide block 4a is parallel with bed die slide block 4b to be installed on by the discharging opening of smelting furnace 1; And be close to discharging opening; Leave flat channel between saidmold slide block 4a and the bed die slide block 4b, the magnesium alloy liquation 3 in the smelting furnace 1 can only flow out the exit of the flat channel of the initiating terminal of said conveyer belt 8 betweenmold slide block 4a and bed die slide block 4b from the flat channel betweenmold slide block 4a and the bed die slide block 4b; Conveyer belt 8 between said mould and the milling train 9 is installed in the temperature control furnace 7; The end of said conveyer belt 8 is installedslewing rollers 11 andcoiling machine 13, and the conveyer belt 8 between said milling train 9 and theslewing rollers 11 is installed in the annealingfurnace 10, and said annealingfurnace 10 is installed on the furnace base support 14 with temperature control furnace 7.Be respectively equipped with cooling air circulation passage 5 on saidmold slide block 4a and the bed die slide block 4b; Said cold air pumps in the cooling air circulation passage 5 through air pump; Be equipped with the circulation water back in the furnace wall of said annealingfurnace 10 and temperature control furnace 7, the exit of said cooling air circulation passage 5 is communicated with through the circulation water back of waste heat recovery pipeline 6 with the furnace wall that is positioned at annealingfurnace 10 and temperature control furnace 7.
Former magnesium alloying in smelting furnace 1 obtains magnesium alloy liquation 3; Magnesium alloy liquation 3 flows into the cooling of the cold air in cooling air circulation passage 5 inmold slide block 4a and the formed flat channel of bed die slide block 4b (cross section of this passage promptly defines width and the thickness after the sheet material depanning) and solidify to formmagnesium alloy plate 12, andmagnesium alloy plate 12 relies on the traction force of milling train 9 to advance; Aftermagnesium alloy plate 12 depannings, in temperature control furnace 7, obtain suitable rolling temperature, get into milling train 9 roll deformations through conveyer belt 8; Behind the hot-roll forming,magnesium alloy plate 12 gets into the residual stress that annealingfurnace 10 is eliminated in the operation of rolling;Magnesium alloy plate 12 goes out annealingfurnace 10 continued and advances throughslewing rollers 11 rolling oncrimping machine 13.
