Quality of the casting and the casting process is closely related to the influence of the solidification of castings. Substances from liquid into solid process called coagulation. Are crystals of solid metal casting, so the metal solidification process known as crystallization. The quality of the casting and mechanical properties depends largely on the proportion of columnar grains and equiaxed grains. steel casting foundry
The casting is cylindrical products whether or equiaxed grains, in addition to the composition of cast alloys, the solidification of the casting. Casting during the solidification process, in addition to pure metals and eutectic composition alloy, generally there are three regions, namely, the solid phase, the solidification and liquid region. Depending on the solidification zone width, the solidification of castings can be divided into the layer by layer solidification of mushy solidification and intermediate solidification in three ways.steel castings manufacturers

2.1 layer by layer solidification of pure metals and eutectic a lloys and the narrow range of crystallization temperature alloys, such as gray cast iron, alloy, silicon brass and low carbon steel, etc., tend to layer by layer solidification mode. Feature is close to the mold wall of the outer layer alloy, once cooled to the temperature of the freezing point or eutectic point in the above-mentioned temperature above the inner layer alloy is still liquid. Solid-liquid interface is clear, smooth, there is no solid-liquid staggered. With the heat transfer to the type of wall, the temperature is falling, another layer of crystalline solid formed. So the solidification process continues, the columnar grain growth within the liquid, until conflict with each other so far. Section heart not yet solidified by the Ministry of liquid metals and low melting point impurities, columnar grains closed.investment casting

2.2 mushy solidification crystallization temperature range of alloys, copper alloys such as aluminum, bronze and ductile iron, high carbon steel, etc., tend to paste solidification mode. Another batch of crystal, these alloys are cooled to the liquidus temperature, the crystallization of the first batch of grain is around the rest of the liquid alloy surrounded by crystal growth is relatively uniform in all directions; temperature decline following the cluster of newly formed particles but also surrounded by the liquid alloy, which makes small grains flooded the section, the solid-liquid staggered, and ultimately generate coarse equiaxed grains in the whole section of the casting; not yet solidified liquid alloy, are a large number of equiaxed grains closed.steel castings

2.3 intermediate solidification of carbon steel, white iron, as well as some special brass, etc., tend to solidification mode in the middle. Between the layer by layer solidification and mushy sol idification, both columnar crystal there, equiaxed grains. Alloy castings solidification zone is not static, it is with the casting temperature, that affect the casting temperature gradient factors affect the coagulation zone size. For example, some alloys manufactured in the sand was the middle of solidification into a metal casting solidification zone width can be reduced

Waste sand trails brick technical issues to be addressed in the past, a lot of people tried to use the waste sand system trails brick. However, due to the low strength of the system to fail. First, the main cause of this problem of waste sand degrees smaller, more cement binder, waste sand in the dust on the strength of cement. In order to solve these problems, we carried out a large number of experimental studies, have carried out more than 100 formulations over 10 kinds of materials forming test, adjust the particle size and the amount of each component, adding special additives, and through a strict variety of testing and data analysis, preferably out of the ideal formula would effectively guarantee the mechanical properties of the brick, the brick to reach the GB pavers of the mechanical index.

The trail brick manufacturing and applications take full advantage of the foundry sand forming the advantages of using homemade equipment has developed a variety of products with fine surface structure and complex shapes. A plant and laying of channel and part of the road, through this process, not only can the use of waste sand and water residue can also use the cupola, to clean up the oxide scale and other waste materials by the use of proven materials for improving the strength of the bricks and The wear resistance has a very good role. The success of this process, which can handle more than 80% of the casting of solid waste.

Waste coke briquette instead of the end part of the coke waste coke powder coke crushing the powder. Foundry coke to join the cupola should be screened out. I Foundry and Casting Plant in each of the production process, can produce thousands of tons of waste coke powder, about 5% of the total coke consumption. Molding technology, these materials are per tonne more than 100 yuan low as the low-level fuel. Coke is the main raw material of the casting production, coke supply in recent years there have been ten years without a comprehensive tensions and spiraling prices, and sometimes the price is more than 2,000 yuan / t. If these materials re-use, and can bring hundreds million worth of economic benefits. Therefore, as soon as possible the development of coke powder molding technology to produce high strength, heat burning, low cost type coke is an urgent need to reduce casting cost.

Thus ability sulfate and acidic media, corrosion penetration, the life expectancy of up to over a thousand years, so this material can be used in corrosive media environment. The role of high temperature: the CBC composite material is based on the ionic bond and covalent connection-b ased, unlike cement-based materials are very sensitive to heat and high temperature hydrogen bond connection, so the fire antiknock ability. Excellent water resistance: the CBC composite internal structure dense, porosity, and external chemicals to water as the carrier is difficult to penetrate inside the material, and therefore very prominent impermeability can be used as a hydraulic material steel casting foundry
