Technical Field

The utility model belongs to the technical field of cooling quenching, and particularly relates to quenching cooling equipment.

Background

The quenching equipment is a control cooling equipment capable of realizing rapid cooling so as to realize rapid cooling of materials below an Ms point at a cooling speed greater than a critical cooling speed for martensite (or bainite) transformation, and then tempering at different temperatures is matched to greatly improve the strength, hardness, wear resistance, fatigue strength, toughness and the like of steel, thereby meeting different use requirements of various mechanical parts and tools.

In order to realize industrial automation, the most used automatic quenching equipment for internal spraying and external spraying is currently used in the market. However, this device has the disadvantage that the cooling rate cannot be adjusted and that it can only be cooled at a single cooling rate. However, for high-carbon high-alloy materials, a single cooling rate can easily cause the quenching cracking phenomenon of the materials.
