Abstract
The invention discloses a smelting process of a bearing block. The smelting process comprises the following steps: manufacturing a mold; manufacturing a fixture; arranging a sprue, a riser and an exhaust port in the mold; carrying out resin sand molding; arranging and closing a resin sand mold; hanging the resin sand mold; putting a sprue cup on the sprue of the mold and putting a riser cup on the riser. The bearing block manufactured by the casting method has the beneficial effects that the probability of appearance of shrinkage cavities is reduced; the requirements of castings are met; the strength and overall performances of the castings are reinforced.
Description
Technical field
The invention belongs to smelting technique field, particularly relate to a kind of melting technology of bearing support.
Background technology
At present, when manufacturing bearing support, need repeatedly to adjust on high-precision lathe by experienced technician just can process qualified parts, efficiency is low, and human factor is large, and cost is high.The melting of bearing support is all adopt water-cooled copper pincers crucible vacuum arc melting button stove to carry out melting, this stove fusion process is complicated, need repeatedly to vacuumize, repeatedly overturn melting, the volatilization of alloying element scaling loss is serious, chemical composition change large and be difficult to control, smelting time is long, simultaneously, also there is the pollution of tungsten alloy electrode alloy, alloying constituent and homogeneity of structure lower, can only the little metal of melting volume, use range is little.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is: existing fusion process is complicated, chemical composition change is large and be difficult to control, smelting time is long.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of melting technology of bearing support, comprising the following steps:
(1) prepare pool furnace charge, pool furnace charge comprises the water of the refractory mortar of 8-25%, the quartz sand of 37-45% and 40-50%;
(2) pool furnace charge is filled in cupola furnace, makes pool stove, and the eye that blows on the stove of the pool;
(3) temperature in cupola furnace is transferred to 400-700 DEG C, pool bake oven is done;
(4) light a fire in cupola furnace, temperature is elevated to 800 DEG C;
(5) feed in the stove of the pool, the material of dress comprises: the old iron of the coke of 5-7%, the new iron of 32-42%, 17-22%, the steel scrap of 35-42%, the phosphorus of 0.2-0.4%, the silicon of 0.6-0.7%, the manganese of 0.6-0.8%, the iron of 0.6-0.7%;
(6) temperature in cupola furnace is elevated to 900-1200 DEG C, the material in Cupola carries out melting;
(7) open cupola furnace, release molten iron, and in molten iron, add the chromium of copper 0.5%-0.75%, the molybdenum of 0.2%-0.5% of 0.5%-0.75%, release the temperature 1250-1450 DEG C during molten iron;
(8) with bull ladle molten iron poured in die cavity and cast.
(3) beneficial effect
Technique scheme tool has the following advantages: the present invention adopts cupola furnace to carry out melting, fusion process controls convenient, conforming product rate is high, change the iron time and melting cycle short, productivity is high, produces chain space compact in design, craft flexibility is good, running cost is low, and pollutant emission is few, improves Working environment and ecotope.This manufacture craft can ensure the high-quality iron liquid of stable acquisition, and cast structure, the performance of generation are good, quality fluctuation scope reduces, qualification rate is high.
