Description

Quick water toughening frock of big tup

Technical Field

The patent of the utility model relates to a tup processing apparatus of breaker high manganese steel material, in particular to big tup quenching frock of breaker high manganese steel material.

Background

The crusher is widely applied to crushing of cement raw materials, production of building aggregate stones, and crushing of various raw materials such as mines, chemical industry and the like. Because the existing crusher is large-sized, the hammer head matched and installed on the crusher is naturally large-sized and heavy. The crusher hammer has heavy single piece and thicker whole thickness. In the heat treatment quenching cooling, the cooling is generally performed in a large circulating water cooling tank. At the stage of heat treatment and quenching of hammerheads, some manufacturers directly use a turnover trolley with a batch of hammerheads to be treated after the trolley comes out of a heat treatment furnace, and pour the hammerheads into a quenching water pool for cooling. Some hammers are arranged in a large frame or placed on a large frame, and the hammers in the frame or on the large frame are directly hung in a quenching water pool for cooling when the hammers are discharged from the furnace. So that the cooling of the hammer head is extremely uneven. Especially when the charging amount is large, a large number of hammers to be cooled directly enter a cooling water pool, and because the discharging temperature of the hammers reaches 1050-1080 ℃, the central parts of the stacked high-temperature hammers are always in a high-temperature environment, so that a large amount of heat cannot be dissipated. Simultaneously, the cooling water is under one hundred degrees temperature, will take place the vaporization, is all covered by the vapor that is vaporized like this around the high temperature tup, and the cooling water can't contact the high temperature tup at all. So the cooling of the hammer head is extremely slow and the cooling of the inner and the outer hammer heads is not even. The purpose of rapidly cooling a large number of hammers stacked at the central part of the stock pile can not be achieved, and the mechanical property and the metallographic structure are unqualified after quenching.

Detailed Description

The water toughening treatment is actually a solution treatment, and is a short name for the heat treatment quenching process of the austenitic manganese steel series materials. The cast structure of the high manganese steel is composed of austenite, carbide and a small amount of pearlite which is a phase change product. The carbides precipitated along the austenite grain boundaries reduce the toughness of the steel, and in order to eliminate the carbides, the steel is heated to an austenite zone temperature (1050-1100 ℃ C., depending on whether the carbides in the steel are fine or coarse) and held for a period of time (1 hour per 25mm wall thickness) so that the carbides in the as-cast structure are substantially all dissolved in austenite, and then rapidly cooled, thereby obtaining a single super-cooled austenite structure. The single super-cooled austenite structure has two main characteristics, namely, one is that the whole matrix has higher impact toughness, the initial hardness is 179-229HB generally, and the part after normal water toughening treatment has the impact toughness of 80-260J/square centimeter; the other characteristic is that the surface of the part with the structure has good impact hardening capacity, and the hardness of the surface hardened part can reach HB500-HB550 under strong impact.

The most important characteristic of the high manganese steel is that under the conditions of strong impact and extrusion, the surface layer is rapidly subjected to work hardening, so that the hardened layer has good wear resistance while the core part still maintains good toughness and plasticity of austenite. This is not reached with other materials. However, high manganese steels exhibit their superiority only under conditions sufficient to form work hardening, and are otherwise poor. Therefore, the high manganese steel is suitable for manufacturing various crusher hammers and plate hammers.

The crusher is widely applied to crushing of cement raw materials, production of building aggregate stones, and crushing of various raw materials such as mines, chemical industry and the like. Because the existing crusher is large-sized, the hammer head matched and installed on the crusher is naturally large-sized and heavy. The crusher hammer has heavy single piece and thicker whole thickness. In the heat treatment quenching cooling, the cooling is generally performed in a large circulating water cooling tank. At the stage of heat treatment and quenching of hammerheads of current manufacturers, some trolleys provided with a batch of hammerheads to be treated are directly used for pouring the hammerheads into a quenching water pool for cooling after coming out of a heat treatment furnace. Some hammers are arranged in a large frame or placed on a large frame, and the hammers in the frame or on the large frame are directly hung in a quenching water pool for cooling when the hammers are discharged from a furnace. So that the cooling of the hammer head is extremely uneven. Especially when the charging amount is large, a large number of hammers to be cooled directly enter a cooling water pool, and because the discharging temperature of the hammers reaches 1050-1080 ℃, the central parts of the stacked high-temperature hammers are always in a high-temperature environment, so that a large amount of heat cannot be dissipated. Meanwhile, the cooling water is vaporized at the temperature of one hundred degrees, so that the periphery of the high-temperature hammer head is covered by the vaporized water vapor, and the cooling water cannot contact the high-temperature hammer head at all. So the cooling of the hammer head is extremely slow and the cooling of the inner and the outer hammer heads is not even. The purpose of rapidly cooling a large number of hammers stacked at the central part of the stock pile can not be achieved, and the mechanical property and the metallographic structure are unqualified after quenching.

The utility model discloses just overcome above-mentioned defect, design a quick water of big hammer and tough processing frock, as shown in fig. 1, including rings 1, hoist and mount chain 2, support chain 3, balanced support 4, tup supporting beam 5 and tup hoist and mount cross bar 6, rings 1 is connected to four angles of balanced support 4 respectively through four hoist and mount chains 2, sets up support chain 3 below four angles of balanced support, installs tup supporting beam 5 between two support chains on the same face, sets up tup hoist and mount cross bar 6 on two tup crossbeams 5.
