Abstract
The utility model relates to a magnesium alloy plate and strip continuous casting and rolling system. The magnesium alloy plate and strip continuous casting and rolling system is characterized in that magnesium alloy cast ingots are preheated and then are smelted in a smelting furnace (1) with protective gas, and then standing is carried out in a standing furnace (2); then, magnesium alloy liquid is conveyed to a front liquid tank (3) through a launder, is maintained at constant temperature in the front liquid tank (3), and enters a casting and rolling machine to be cast and rolled through a casting nozzle (4); a high-temperature resisting filter (7) is arranged in a liquid flow channel in the standing furnace (2) or the front liquid tank (3). According to the magnesium alloy plate and strip continuous casting and rolling system, impurities absorbed from furnace linings, furnace gas, solvents, furnace charge and operating tools are removed through the high-temperature resisting filter (7) arranged in the liquid flow channel in the standing furnace or the front liquid tank, the impurities are prevented from being mixed into cast and rolled strips along with metal melt, and the defects of slag inclusion, oxidation films and the like are avoided. The mechanical performance and the anti-corrosion performance of products are improved significantly. Therefore, through the magnesium alloy plate and strip continuous casting and rolling system, the content of the slag inclusion is reduced effectively, and finally high-quality plates are produced.
Description
Technical field
The utility model relates to a kind of magnesium alloy board continuously-casting system, belongs to magnesium alloy board continuous casting rolling technology field.
Background technology
Casting also claims molten condition rolling, is casting method and the manufacturing process of combining of milling method.
The magnesium alloy board continuous casting and rolling cleaning molten technique of prior art is as follows: magnesium alloy ingot is through preheating after processing, carries out melting, leaves standstill in the smelting furnace of protective gas, standing furnace; Then be transported to front liquid case through chute, in front liquid case, keep liquid magnesium alloy constant temperature, then enter casting and rolling machine casting through lip, carry out warm-rolling and the cold rolling finished product sheet material of producing desired thickness finally by finishing mill.
But magnesium alloy ingot, in the time of melting, can absorb impurity from furnace lining, furnace gas, solvent, furnace charge and operation tool, once these impurity are sneaked in cast strip with metal bath, will cause the defect such as slag inclusion, oxide-film.It significantly reduces the mechanical property of goods and corrosion resistance.
How to reduce the impurity content in magnesium alloy board, thereby improve its mechanical property and corrosion resistance, become the technical barrier of this area.
Utility model content
The utility model technical issues that need to address are: in the technique that existing magnesium alloy board continuous casting and rolling is produced, easily contain the defect such as slag inclusion, oxide-film in strip, cause mechanical property and corrosion resistance significantly to reduce.
The utility model is taked following technical scheme:
A kind of magnesium alloy board continuous casting and rolling technique, magnesium alloy ingot, through preheating after processing, carries out melting in the smelting furnace 1 of protective gas, in standing furnace 2, leaves standstill; Then be transported to front liquid case 3 through chute, in front liquid case 3, keep liquid magnesium alloy constant temperature, then enter casting and rolling machine casting through lip 4; In the fluid course of described standing furnace 2 or front liquid case 3, high-temperature resistant filter 7 is set.
Further, described high-temperature resistant filter 7 is ceramic foam filters.Floamed ceramics filtrating piece has following effect to the seizure of field trash: filtration---and each hole mouth place at filter stops inclusion particle; Precipitation---metal bath when the filter, some very fine foreign matter particle be deposited in some corners of filter inside and remove; Suction-operated---ceramic foam filter inwall is to solid-state fine be mingled with or liquid state is mingled with adsorbable removal.The comprehensive function that these are machine-processed, can make foam ceramic filter reach fabulous effect, not only can filter microinclusions particle in alloy melt, and can filter liquid flux and be mingled with.
Further, adopting main component is magnesian ceramic foam filter.In ceramic foam filter, MgO filter not with magnesium fusant reaction, therefore, can magnesium melt not produced and be polluted, and because the liquid flux angle of wetting in MgO and liquid magnesium alloy is very little, MgO floamed ceramics filtrating piece very easily adsorbs the flux drop in magnesium alloy, thereby makes Mg alloy castings exempt flux inclusion defect.
Further, described high-temperature resistant filter 7 is stainless steel wire web filters.
Implement a system for above-mentioned magnesium alloy board continuous casting and rolling technique, comprise refining smelting furnace 1, standing furnace 2, front liquid case 3, lip 4, casting and rolling machine 5, described high-temperature resistant filter is arranged at the inside of standing furnace 2.
Implement a system for above-mentioned magnesium alloy board continuous casting and rolling technique, comprise refining smelting furnace 1, standing furnace 2, front liquid case 3, lip 4, casting and rolling machine 5, described high-temperature resistant filter is arranged in front tank 3.
The utility model is by arranging high-temperature resistant filter in the fluid course in standing furnace or front liquid case, thereby remove the impurity absorbing from furnace lining, furnace gas, solvent, furnace charge and operation tool, avoid these impurity to sneak in cast strip with metal bath, avoided the defect such as slag inclusion, oxide-film.Mechanical property and the corrosion resistance of goods are significantly improved.Therefore, by the utility model, effectively reduce the content of field trash, final production goes out the sheet material of high-quality.
The beneficial effects of the utility model are:
1) impurity such as slag inclusion, oxide-film in effective filtering magnesium alloy board.
2) greatly promote mechanical property and the corrosion resistance of magnesium alloy board.
3) preferred version is taked ceramic foam filter, thoroughly removes the impurity such as slag inclusion, oxide-film by filtering, precipitate, adsorb triple role.
4) to take main component be the ceramic foam filter of MgO to preferred version,
5) not with magnesium fusant reaction, therefore, can magnesium melt not produced and be polluted, and because the liquid flux angle of wetting in MgO and liquid magnesium alloy is very little, MgO floamed ceramics filtrating piece very easily adsorbs the flux drop in magnesium alloy, thereby makes Mg alloy castings exempt flux inclusion defect.
