Sand mold steel casting equipment

Abstract

The invention discloses sand mold steel casting equipment. The sand mold steel casting equipment comprises two tightly attached molds, wherein molten steel is poured in the two molds, nitrogen elementwith the adding amount being 0.1-0.3% is added into the molten steel on the basis of original material chemical components, the same side of the two molds is provided with an installation plate, andan installation table is fixedly installed on one side of the installation plate. The alloy element-nitrogen element with the adding amount being 0.1-0.3% is added on the basis of the original material chemical elements so as to achieve the effects of solution strengthening when nitrogen is solidly dissolved in an austenite, accordingly the purpose of improving the mechanical performance of steelis fulfilled, the mechanical property and the stability of the material are improved, the production cost is lowered, smooth operation of production is ensured, convenient demolding can be achieved through two clamping boards without adopting structures such as gears, demolding can be more convenient and rapider, the quality of a product is guaranteed, meanwhile, the equipment can clamp molds in different sizes, the universality of the equipment can be improved, and the equipment satisfies the requirements of people.

Description

technical field [0001] The invention relates to the technical field of sand mold steel casting equipment, in particular to sand mold steel casting equipment. Background technique [0002] Cast steel (cast steel) refers to the steel specially used to manufacture steel castings. When the strength requirements of castings are high and cast iron cannot meet the requirements, cast steel should be used. However, the fluidity of molten steel in cast steel is not as good as that of cast iron, so the casting structure The thickness should not be too small, and the shape should not be too complicated. Controlling the silicon content to the upper limit can improve the fluidity of molten steel. [0003] The publication number is CN106938319B, which discloses a separate sand casting mold. A mold and a support rod are arranged on the support base plate. There is a first gear on the first screw rod, and a second gear on the second screw rod. The existing cast steel material super austeni...

Problems solved by technology

[0003] The publication number is CN106938319B, which discloses a separate sand casting mold. A mold and a support rod are arranged on the support base plate. There is a first gear on the first screw rod, and a second gear on the second screw rod. The existing cast steel material super austenitic stainless steel (CN7M), because the size of the test block is particularly large, according to this regulation The chemical composition ratio, control, production, after heat treatment, often yield, tensile properties are not stable enough, can not meet the standard requirements, what's more, the product still cannot meet the requirements after secondary heat treatment, which seriously affects the production cost and The product delivery time may even cause the product to be scrapped. At the same time, the device uses gears and other structures to demould. When the gears are worn, it may cause demoulding failure, which will affect the quality of the product. At the same time, it cannot adapt to molds of different sizes. , there is room for improvement
