Nitrogen purity regulation of multi-purpose carburizing furnace

Nitrogen purity regulation of multi-purpose carburizing furnace

1. The production line of the van type controllable atmosphere multi-purpose furnace is mainly used for steam nitriding, carbonitriding, re-heating after nitriding heat treatment of the product workpiece under controllable atmosphere and heat treatment and quenching under maintenance atmosphere. The actual operation of the machine and equipment must be thoroughly reliable, immediately concise, the selection of electronic computer automatic control system for the whole process, the reliability of the processing process is good, in the case of power failure or other unexpected conditions, can complete automatic nitrogen charging, and can be carried out according to the manual actual operation process, in order to ensure proper actual operation and product quality.

2. Tempering furnace with maintenance atmosphere is used for quenching and time-sensitive quenching of product workpieces (heating output power should be adjustable for high and low temperature test with different temperature segments, including maintenance atmosphere).

3. Cleaning equipment is used for cleaning and air drying of product workpieces before nitriding, carbonitriding and after heat treatment. The cleanliness of the product workpiece after cleaning and air drying shall meet the requirements of nitriding and carbonitriding, and the product workpiece is corrosion resistant and has no harm to the quality of the heat treatment process of the next process.

4. Loading, unloading, handling and charging machine is used for loading and unloading and handling of multi-purpose controlled atmosphere furnace, tempering furnace and cleaning equipment to understand the transmission of intermediate product workpieces of each process flow of the production line. The loading and unloading and handling materials of the personal workshop of the machine equipment can be carried out precisely in accordance with the specified position.

All machinery and equipment of the production line must be new and upgraded machinery and equipment (including all parts, electronic devices and accessories). By no less than the national industry standards of excellent and reliable raw materials, production processes and standards manufacturing; The tenderer shall have more than two years of application work experience in the coal mining machinery manufacturing industry or similar manufacturing industry in China.
