Embodiment Construction

[0022] As shown in the figure, a strip-shaped metal continuous quenching cooling system is mainly used for quenching and cooling of saw blades. It includes a cooling tank 1 and a cooling liquid circulation mechanism for supplying cooling liquid to the cooling tank 1. The cooling tank 1 is used to hold the cooling liquid. , When the strip metal passes through the cooling liquid in the cooling tank, it is cooled.

[0023] The cooling tank 1 is roughly rectangular, and its opposite side walls are respectively provided with a feed inlet 101 and a discharge outlet 102 at the same height. In this embodiment, there are two feed inlets and two discharge outlets, and they correspond to each other. Of course, the cooling tank 1 can be in other shapes, such as circular. When cooling, the strip metal can pass through the feed port 101 and the discharge port 102 horizontally. A strip metal guide mechanism 2 and a straightening mechanism 3 are arranged in the cooling tank 1 .

Abstract

The invention discloses a continuous quenching cooing system for strip metal, which comprises a cooling tank for containing the cooling liquid and a cooling liquid circulation mechanism, wherein the side wall of the cooling tank is provided with a material outlet and a material inlet for the strip metal to pass horizontally; and a strip metal straightening mechanism on the same line as the material outlet and material inlet is arranged in the cooling tank. The system disclosed by the invention cools the strip metal by use of the cooling liquid in the cooling tank, and ensures that the strip metal is not bent through the straightening mechanism; due to the lubrication of the cooling liquid, scratch is not left even if friction exists between the straightening mechanism and the strip metal; and moreover, as the entire section of the saw blade is immersed in the cooling liquid, the cooling temperature is uniform, and the strip metal can not deform.

Description

technical field [0001] The invention relates to a quenching cooling system, in particular to a strip-shaped metal continuous quenching cooling system. Background technique [0002] The quenching of steel is to heat the steel to a certain temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keep it warm for a period of time to make all or part of the austenite 1, and then cool it at a temperature greater than the critical temperature. The cooling speed is a heat treatment process for martensite (or bainite) transformation by rapidly cooling below Ms (or isothermal near Ms). Quenching can improve the hardness and wear resistance of metal workpieces. Cooperating with tempering at different temperatures can greatly improve the strength, toughness and fatigue strength of metals, and can obtain the coordination between these properties (comprehensive mechanical properties) to meet different requirements. usage requirements.
