Customized Design Solution

Haitian Heavy Industry is developing and designing burner nozzle castings. Through 3D printing, it has solved the problem of complex product structure, high acceptance and installation requirements. The heat dissipation blade is less than 10mm, the burner nozzle is φ8mm, and the material is Ni25Cr20 heat-resistant steel. Traditional sand casting methods are difficult to meet the requirements of accuracy and delivery time. In order to shorten the development cycle and improve product accuracy, the use of 3D printing technology reduces the difficulty of process and mold making, and makes the product accuracy and appearance far exceed customer acceptance requirements.

High Chromium Cast Iron Solution

Haitian specializes in the production of high-chromium cast iron wear-resistant castings, which are mainly used for wear-resistant parts in engineering machinery, especially in concrete mixing plants. The working environment of concrete mixing plants is extremely harsh, and the mixing blades, linings and other parts need to withstand the long-term impact and wear of concrete and sand and gravel. Therefore, the requirements for wear resistance are extremely high. Take Haitian Heavy Industry Co., Ltd. for example, it has successfully developed a series of spiral blade wear-resistant castings suitable for concrete mixing plants.

Alloy Steel Solutions

Haitian Heavy Industry Company has developed and produced a 1150mm diameter alloy steel grinding ball, which is specially used in medium-speed coal mills in power plants to crush coal blocks. This type of grinding ball needs to operate in a high-wear and high-impact environment and has excellent wear resistance and impact resistance to ensure the efficient operation of the power plant and the long-term use of the equipment.

Ceramic Composite Solutions

Haitian Heavy Industry has developed a ceramic blow hammer, which is made of high-chromium cast iron embedded with ceramic particles. It is mainly used in mining crushers to crush ore. The mining environment is harsh, and the crushing equipment needs to withstand high impact and strong wear. Therefore, this ceramic blow hammer is designed to significantly improve wear resistance and service life.

Lightweight Design Solutions

Haitian is committed to producing wear-resistant castings for construction machinery and has designed a high-chromium cast iron elbow for concrete pump trucks. In order to improve product performance and reduce costs, the team has made a lightweight design on the elbow structure, thickening it at the bend to improve wear resistance, while thinning it at both ends to reduce the overall weight. This design not only reduces the weight of the product, but also extends its service life, effectively improving the product's cost-effectiveness.
