Novel high-temperature carburizing equipment

Abstract

The invention relates to a new type of high temperature carburizing equipment, comprising a carburizing cabin, a carburizing cabin cover is arranged on the carburizing cabin, a plurality of brackets are arranged in the carburizing cabin, and each bracket is provided with a There is a carburizing tank, and the workpieces to be processed are placed in the carburizing tank, and high-frequency coils are arranged on the outside of a plurality of the carburizing tanks, and the high-frequency coils are arranged in the carburizing cabin and connected to A high-frequency machine, the carburizing cabin is provided with an air inlet and an air intake hole; it also includes a thermocouple, the thermocouple passes through the side wall of the carburizing cabin and is located inside the carburizing cabin, the A sealing ring is provided at the position where the thermocouple is connected to the side wall of the carburizing cabin. With the above-mentioned structure, the new high-temperature carburizing equipment can precisely control the heating temperature and position, heating and cooling speed, carburizing environment, product composition and carburizing layer thickness, which greatly improves the stability of the carburizing process.

Description

technical field [0001] The invention relates to a carburizing equipment, in particular to a novel high-temperature carburizing equipment. Background technique [0002] The existing carburizing technology refers to a chemical heat treatment process in which the metal is heated in a carburizing medium and kept warm so that carbon atoms can penetrate into the surface layer in order to increase the carbon content of the surface layer of the metal material and form a certain carbon concentration gradient. Carbon concentration and other properties. Commonly used are solid carburizing and gas carburizing. Among them, solid carburizing is the earliest carburizing method, and it is widely used because the thickness of carburizing layer is easier to control. Traditional solid carburizing equipment has fewer workpieces at one time, long carburizing time, difficult temperature control, inaccurate heating position, unstable product structure and composition, and cumbersome and time-cons...

Problems solved by technology

Traditional solid carburizing equipment has fewer workpieces at one time, long carburizing time, difficult temperature control, inaccurate heating position, unstable product structure and composition, and cumbersome and time-consuming operation; for example, Yao Shibin once reported a thoriated tungsten The structure of the cathode carbonization chamber, the structure of this equipment is complex, only one thoriated tungsten electrode can be fixed at a time, and the thickness of the carbonization layer is controlled by the carbonization current and time, but the specific temperature in the carbonization chamber cannot be determined
