Petrochemical bearing forging is an important part in the field of machinery manufacturing, and its production process has an important impact on the quality and performance of the product. In this paper, the production process of petrochemical bearing forgings will be illustrated in detail, and some technical details will be added, such as how to control the temperature in the forging process.
Production process diagram
Raw material preparation
Use high-quality steel as raw materials to ensure that the chemical composition and mechanical properties of the materials meet the requirements. Surface treatment of raw materials, such as cleaning, rust removal, etc., to ensure surface quality.
forge
The raw material is heated to a suitable temperature and free or die forging is performed to deform the material and achieve the desired shape. The forging process needs to control temperature, pressure and other parameters to ensure product quality.
How to control the temperature during forging:
(1) Preheating: Before forging, the raw materials are preheated to improve the plasticity and toughness of the material and reduce the deformation resistance. The preheating temperature is determined according to the material type and forging process requirements, and is generally controlled within the appropriate temperature range.
(2) Heat preservation: in the forging process, maintain the appropriate forging temperature, so that the material is fully deformed and flowing. The holding time is determined according to the material type and forging process requirements, and is generally controlled within the appropriate time range.
(3) Rapid cooling: After forging, rapid cooling measures are taken, such as water cooling, air cooling, etc., so that the material is quickly cooled to room temperature to prevent cracks or deformation of the material.
Heat treatment
Heat treatment of forged bearing forgings, such as quenching, tempering, etc., to improve the hardness and wear resistance of the material. In the heat treatment process, temperature, time and other parameters should be strictly controlled to ensure product quality.
How to control the temperature during heat treatment:
(1) Quenching temperature: according to the material type and heat treatment process requirements, choose the appropriate quenching temperature. Too high quenching temperature may lead to overburning or deformation of the material, too low may affect the hardness and wear resistance of the material.
(2) tempering temperature: tempering treatment after quenching to eliminate internal stress and improve the toughness of the material. The tempering temperature is determined according to the type of material and the requirements of the heat treatment process, and is generally controlled within the appropriate temperature range.
process
The bearing forgings after heat treatment are processed, such as turning, milling, grinding, etc., to achieve the required size and accuracy. In the process of processing, attention should be paid to tool selection, cutting parameters, etc., to ensure product quality.
Inspection and packing
Check the bearing forgings after processing, such as size, hardness, appearance and so on. Qualified bearing forgings are packed and ready for delivery.
Strictly control the quality of raw materials to ensure that the chemical composition and mechanical properties of materials meet the requirements.
Strict control of forging and heat treatment process temperature, pressure and other parameters to ensure product quality.
Pay attention to the selection of tools, cutting parameters, etc., to avoid overheating, overburning and other phenomena.
Strengthen inspection links to ensure that product quality meets the requirements.
Pay attention to moisture-proof, rust-proof and other measures during the packaging process to ensure the quality of products during transportation and storage.
The production process of petrochemical bearing forgings, including raw material preparation, forging, heat treatment, processing, inspection and packaging, are introduced in detail by means of diagrams. In the production process, the quality parameters of each link should be strictly controlled to ensure that the product quality meets the requirements. At the same time, strengthen the quality control and management in the production process, improve the production efficiency and product quality level.
