Lost Foam Casting

Our foundry is specialized in producing heat-resistant alloy castings and wear-resistant alloy castings with an annual output of 2,500 tons of production capacity. We adopt eco-friendly casting technologies which are lost foam casting technology and shell mold casting technology.

Lost Foam Casting Technology adopts the foam mold similar to the size and shape of the casting, coats it with refractory coating, dries and fixes it in quartz sand with vibration, pours it under negative pressure, the mold is gasified and occupied with liquid metal, and forms the casting after solidification and cooling. Advantages of this casting technology are accurate molding, no joint surface, no sand core, no flash, burr and draft angle as well as low dimensional error, low mold cost, and easy process adjustment and so on.

Shell Mold Casting

Shell Mold Casting Technology suits for the production of large batches, high dimensional accuracy requirements, thin walls and complex shapes of various alloy castings. Its metal casting process similar to sand casting, in that molten metal is poured into an expendable mold. which is then heated and filled with molten metal to produce precise metal parts. The characteristics of this kind of castings are high surface finish, high dimensional accuracy, and good material properties etc.

Wear-Resistant And Heat-Resistant Castings

Wear-resistant castings and heat-resistant castings are a special class of casting which are designed with two important attributes in mind: wear resistance and heat resistance. Such castings are widely used in various industries, especially in environments where high temperatures and abrasion are required.

Main features of wear-resistant and heat-resistant castings:

High temperature resistance

This type of casting can work for long periods of time in a high-temperature environment without failing, and can usually withstand high temperatures ranging from hundreds to thousands of degrees Celsius.

Abrasion resistance

Products have excellent abrasion resistance and maintain their shape and dimensional stability for long periods of time in high-wear environments.

Corrosion resistance

Some wear-resistant and heat-resistant castings also have good corrosion resistance, and can work stably in corrosive media such as acid and alkali.

Technology

As a company that is dedicated to provide products that can perfectly cater to all your needs. We have a team of highly experienced engineers who can offer you with energy audits, onsite product inspections, maintenance works including system operational support and product installation suggestion.

The production process of wear-resistant and heat-resistant castings includes smelting, casting, heat treatment and other steps. In smelting, high-temperature equipments, such as electric arc furnaces or induction furnaces are usually used to smelt the raw material into molten steel. When casting, molten steel is poured into a mold and formed after it cools and solidifies. Heat treatment is an important step to improve the performance of castings, the structure and properties of castings can be adjusted by normalizing, quenching and tempering, annealing and so on.

There are many types of wear-resistant and heat-resistant castings, including high-manganese steel castings, high-chromium cast iron etc. High manganese steel castings have extremely high wear resistance, and are mainly used for wear-resistant parts and impact-resistant parts in mining, coal mining, cement, steel and other industries. High-chromium cast iron has extremely high wear resistance and heat resistance, and is suitable for wear-resistant parts, heat-resistant parts, anti-corrosion parts and other parts in mining, cement, power and other industries.

In conclusion, wear-resistant and heat-resistant castings are important industrial materials that play a crucial role in multiple fields. With the advancement of technological and industrial development, the performance and application range of wear-resistant and heat-resistant castings have been increasingly.

Hitz Zosen Mechanical Grate Technology

Take waste incineration grates for example, we can offer controls for better firing, additional support for air permit testing and upgrades for combustion system as well combustion tuning and retrofits for a wide range of projects. Optimizing the grate structure can improve the grate strength, avoid internal defects, promote the movement rolling and burning of garbage, and improve combustion efficiency. Adjust the porosity of grate block, control the amount of ventilation and burning speed of garbage in the furnace. Taking composition optimization to improve the material's high temperature resistance, oxidation resistance, wear resistance, etc, according to different workine conditions to provide reasonable suggestions.
