Sand casting is sand as the main molding materials, casting the traditional casting technology. Sand mold casting using molding materials cheaper and casting is simple, can adapt the casting sheet production, mass production and mass stainless steel toilet production, has long been a casting production base Technology. Gravity casting. Refers to the metal liquid (copper) injection under gravity casting technology, also known as metal casting. Is made of heat resistant alloy steel casting with hollow casting mould of modern technology. Casting of copper alloy. Raw material for casting of copper alloy for leading products, has a good casting properties, mechanical properties, corrosion resistance, and fine casting organization, compact structure. Alloy nameplate according to GB/T1176-1987 cast copper alloy process conditions choose, copper content (58.0 ~ 63.0) %, is the ideal leading casting material.
The tap casting process is briefly. First, in automatic hot core box shoot core machine, production sand core spare, copper alloy smelting (resistance furnace smelting equipment), copper alloy as part of the molten state, sampling for chemical analysis of copper alloy test pieces, for real Laboratory analysis and spectrum analysis, chemical titration after confirm copper alloy stainless steel squatting pan chemical composition meet the requirements, for casting (pouring equipment for metal mold gravity casting machine), cooling solidification open mold unloading after cleaning the export, all resistance furnace in the copper water after pouring, self-checking The cooling of the casting into the shakeout machine roller ceramic sand cleaning. Next casting (excluding stress annealing heat treatment), the purpose is to eliminate the internal stress of castings produced.
Will be more ideal blank into the shot blasting machine casting billet, guarantee the lumen is not accompanied by sand, gold Cuttings or other impurities. For fully enclosed casting billet, the air in the water test box stainless steel shower tray sealing and diaphragm seal. Finally through the analysis of the quality inspection check classification into the Treasury.
Detailed introduction bibcock production casting processes. What is a casting. Usually refers to using the molten alloy material product, the method of injected liquid alloy casting made in advance, cooling and solidification, and get the required shape of the weight of blank and parts. gold Mold casting. Metal casting, also known as hard casting, it is by pouring liquid Time Delay Tap metal casting, metal casting, casting method. Cast molding is made from metal, can be reused many times (hundreds to thousands of times). Metal mold casting can now produce castings,In terms of weight and shape has certain restrictions. Black metal, for example, only is a simple shape casting casting weight cannot too big wall thickness is also limited, not casting small casting wall thickness.
