Valve Pipe Casting Improve Production Capacity

Valve Pipe Casting industry in technology, quality and price, relative to Southeast Asia and the Middle East and other countries, have a great advantage, export prospects are very gratifying. And foreign-funded enterprises to enter China, the Valve Pipe Casting of the resale and export will also be an important part of China's Valve Pipe Casting exports. Next by the precision Valve Pipe Casting manufacturers to tell you about the precision Valve Pipe Casting stainless steel valve heat treatment process:

Dense Valve Pipe Casting manufacturers to introduce you to precision Valve Pipe Casting stainless steel valve heat treatment process

First, the precision Valve Pipe Casting manufacturers - precision Valve Pipe Casting all annealing: the Valve Pipe Casting is heated to the austenite temperature range and save a period of time, and then with the furnace cooling method to teach the whole annealing heat treatment, referred to as annealing. Heating, to ensure that the Valve Pipe Casting does not produce deformation and cracking under the premise. Win fast heating, a set to improve production capacity. Heating speed depends mainly on the chemical composition of steel. The cross section of the Valve Pipe Castings is small and the shape of the Valve Pipe Castings, the steel contains high carbon content. Poor thermal conductivity, the allowable heating rate is low. The greater the cross section of the shoulder, the greater the temperature difference in the inner layer when heated, the greater the thermal stress caused, so the heating rate is slower. Complex shape, section thickness difference between the Valve Pipe Casting, the heating rate should be slower.

Second, the normalizing in the heat treatment: normalizing the heating temperature and holding time and the same annealing, the difference is that the holding time is reached, the Valve Pipe Castings on the air cooled to room temperature.

Third, the precision Valve Pipe Casting manufacturers - precision Valve Pipe Casting plus fire plus tempering: In order to improve the structural properties of the normal, you can use in the normalizing after the tempering of the heat treatment process. Tempering temperature of 500-650 degrees, are high temperature tempering, insulation to 2-3 hours.

Fourth, quenching: quenching after the workpiece hardness and easy to deformation, should be arranged in the finishing stage before the grinding process.

5, carburizing: Valve Pipe Casting mold surface decarburization phenomenon, is a more serious defects. Decarbonization will reduce the carbon content of the surface layer just before. For medium carbon steel and high carbon steel is more obvious. Heat treatment greatly increases the performance of precision machinery Valve Pipe Castings. All the company's Valve Pipe Casting products are heat treatment. But the heat treatment process is more complex.

Precision foundry manufacturers today for everyone to introduce here, hoping to help everyone, on the precision Valve Pipe Casting and other information.
