CHAENG has a variety of engineering and technical personnel such as casting, non-destructive testing, welding, materials, and quality management of steel castings. In all aspects of steel casting processing and manufacturing (design, process, materials, welding, nondestructive testing, product inspection, Standardization, measurement, quality management, etc. ), CHAENG sets up responsible engineers and managers for the formation of a relatively complete quality assurance system.

These engineers are backbone technical talents with rich practical experience and rely on mature and advanced management models—process, informationization, and specialization—to provide users with a series of services ranging from rough casting to finished products and a full range of solutions.

CHAENG has introduced two 60-ton alkaline electric arc furnaces, four large-scale natural gas heat-treating furnaces, and other auxiliary facilities such as oxygen production stations, air compressor stations, natural gas stations, and CO2 stations. Also introduced the German OBLF company GS1000 vacuum direct reading spectrometer, carbon and sulfur high-speed analyzer, microcomputer three-element high-speed analyzer, digital ultrasonic flaw detector, multi-purpose magnetic particle flaw detector and other physical and chemical testing facilities, lever type universal strength testing machine, hammering type Tensile testing equipment such as prototype machine; using CAE software to simulate the casting process is a new level of casting process.

In order to ensure that the materials of steel castings meet the standards, CHAENG adopts a computer multi-element analyzer, which can meet the quantitative detection requirements of C, S, Mn, P, Si, Cr, Ni, Mo, Cu, Pb, Sb, Ba, Ti, V, Al, W, Nb, Mg, Co in high, medium and low alloy steel raw materials. The highly stable data acquisition system ensure the precision and accuracy of the measurement.

Production process of rotary kiln support roller is:

The first step: Simulation and modeling

Before casting, numerically simulate the casting process by CAE software to analyze the molding process, predict and optimize the product quality.

The second step: pouring and heat treatment

Sample hot metal and perform the spectral analysis. After qualification, start pouring according to the principle of "low temperature and quick casting", and the pouring time and temperature shall be recorded.

The third step: polishing and flaw detection

CHAENG uses advanced detection equipment for non-destructive testing to ensure the internal quality of supporting roller, strictly stop any defective goods from leaving the factory. CHAENG steel castings can meet level-two flaw detection standards.

CHAENG has the advanced casting equipment, strictly follows the national lever-2 detection standards, and executes 360° all-round nondestructive testing system, to ensure the reliable quality and long service life of steel castings. CHAENG is hailed as "high cost-effective steel castings manufacturer".

CHAENG is steel casting base with complete production systems. The above four quality assurance systems strictly guarantee the internal quality and external aesthetics of rotary kiln support rollers.
