Time-controlled quenching equipment water spray pipe system

Abstract

The invention discloses a water spraying pipe system of a novel time-controlled quenching device. Through the design of a special water spraying pipe structure of the water spraying pipe system, all-direction remote jetting can be achieved, it is effectively guaranteed that quenching media can be evenly jetted to all section parts of a semi-autogenous mill cylinder lining plate, it is guaranteed that the lining plate can be quenched in all directions, the cooling speed of different sections of the lining plate is uniform and consistent, it is effectively guaranteed that the cooling speed of the section parts of the lining plate is larger than the critical cooling speed, and more martensite (or lower bainite) structures are obtained; the hardenability, the hardness, the abrasion resistance, the impact toughness and other performance of the lining plate are obviously improved, the tenacity of a center part is guaranteed, the comprehensive using performance of the lining plate is improved, the service life of the lining plate is prolonged, and the lining plate replacing time is prolonged; and resources are saved, the new national energy-saving and environment-friendly development concept is met, and very high practical value and popularization value are achieved.

Description

technical field [0001] The invention relates to the field of metal heat treatment mechanical equipment, in particular to a time-controlled quenching equipment water spray pipe system for a wear-resistant material liner. Background technique [0002] The speed of national mining development is closely related to the advanced level of mining engineering equipment. Some mining engineering equipment, such as autogenous mills and semi-autogenous mills, have also been introduced and developed in China. Among them, the semi-autogenous mill has been put into use, and industrialized production has been realized, which has effectively improved the development speed of China's mining industry. According to the crushing principle, the cylinder liner of the semi-autogenous mill is easy to wear and needs to be replaced frequently, which increases production costs and reduces work efficiency. Therefore, it is necessary to improve the comprehensive performance of the semi-autogenous mill c...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of easy wear and tear of the cylinder liner of the semi-autogenous mill through the automatic completion of the heat treatment process of the equipment, improve the performance and service life of the liner, and propose a method that can make the liner perform all-round The water spray pipe system structure of the quenching heat treatment process equipment can realize all-round spraying, effectively ensuring that each section of the lining plate can spray the quenching medium evenly, so that the cooling speed of different sections of the lining plate is uniform and consistent, and effectively guarantees that the lining plate The cooling rate of different sections of the plate is greater than the critical cooling rate, and more martensite (or lower bainite) structure is obtained, which significantly improves the hardenability, hardness, wear resistance and impact toughness of the lining plate. And it ensures the toughness of the core, improves the comprehensive performance and service life of the lining plate, and improves the quenching efficiency of the lining plate, which is conducive to mass production and saves energy and production costs. It is in line with the new concept of national energy-saving, environmental protection and green development, and has great Good practical value and promotion value
