Abstract
The invention relates to a mining scraper which is commonly used in a scraper conveyor and a transfer conveyor, in particular to a heat treatment method of the mining scraper. The heat treatment method is characterized by comprising the following steps: the scraper is placed on a conveyor belt of a scraper quenching machine tool, heated to 880-920 DEG C after reaching an induction coil area, cooled rapidly by spraying water after reaching a water spray area, and then discharged after reaching a discharge area. The heat treatment method using the technical scheme provided in the invention has the technical effects as follows: the product quality is guaranteed, the comprehensive performance of the scraper is improved, ends are wear resistant and the service life is prolonged; two ends can be machined per time by adopting closed-coil medium-frequency quenching, thus improving the efficiency by 1 time compared with the original manufacturing method; and heating time and water spray time are controlled by programs, technological parameters are effectively executed, the scraper is subject to surface strengthening by induction heating so as to ensure that the strength and the hardness of a scraper matrix can meet the requirements, and a hardening layer is distributed rationally without hardening cracks, thus effectively guaranteeing the quality of parts.
Description
Technical field
The present invention relates to a kind of mining scraper plate that is usually used on scraper conveyor, the elevating conveyor, especially mining scraper plate heat treating method.
Background technology
Scraper plate also is a consumable accessory as the main parts size of scraper conveyor, elevating conveyor, and consumption is very big.Scraper plate when normal the use, two ends and scraper conveyor ledge and in plate produce friction, it is very serious wear and tear, raising scraper plate termination hardness can improve scraper plate work-ing life greatly, promotes the work-ing life of scraper plate conveying complete machine simultaneously, thereby increases the coal amount.
And traditional scraper plate heat treating method has the following disadvantages: 1, can only handle an end, a scraper plate is handled 2 times at every turn, and efficient is lower.2, adopt the time relay to add Artificial Control, processing parameter can not effectively be carried out, and part quality can not get effective assurance.3, at every turn can only 1 workpiece of clamping, labour intensity is big.
Summary of the invention
The purpose of this invention is to provide a kind of dependable performance, make mining scraper plate thermal treatment manufacture method easy, energy-conservation, with low cost.
For achieving the above object, the technical solution used in the present invention is:
A kind of mining scraper plate heat treating method, its special feature is, comprise the steps, scraper plate is placed on the travelling belt of scraper plate quenching machine, be heated to 880 ℃-920 ℃ after arriving the ruhmkorff coil district, arrive the water spray district then, water spray makes the workpiece quick cooling, arrives discharge zone then and unloads and get final product.
Its middle scraper translational speed is 0.04-0.05m/s, and be 180-240 second heat-up time, and be 60-70 second cooling time.
Adopt technical solution of the present invention to have following technique effect: 1, help guaranteeing quality product, the technical program helps improving the scraper plate over-all properties, and the termination is wear-resisting, improves work-ing life, reaches advanced world standards.2, adopt encapsulated coil medium frequency quenching, can handle two ends at every turn, a scraper plate is only handled 1 time, raises the efficiency 1 times than former manufacture method.3, heating, water spraying time are by time variable control, and processing parameter can effectively be carried out, and scraper plate is carried out the induction heating surface strengthening, can meet the demands to guarantee scraper plate matrix strength, hardness, and quench-hardened case distributes rationally, no quenching crack, and part quality is effectively guaranteed.But 4,4 parts of clamping once, the operator can have to be interrupted and has a rest, and has realized semi-automatic work production, and labour intensity reduces greatly.
Embodiment
Embodiment 1:
Length 800mm scraper plate, transfer to by the thermal treatment unit, access 800mm scraper plate quenching program, the lathe dry running once, check ruhmkorff coil, whether water spray ring leaks, 4 scraper plate parts of a clamping, power-on is carried out this program, the lathe conveyer belt, scraper plate arrives in the ruhmkorff coil district with 0.04m/s speed, and scraper plate begins heating, 200 seconds heat-up times, this moment, scraper plate two ends temperature reached 900 ℃, scraper plate arrives the water spray district with 0.04m/s speed once more, and water spray ring is opened immediately, and the scraper plate two ends is cooled off fast, be 70 seconds cooling time, after cooling finished, water spray ring was closed, and scraper plate arrives discharge zone and carries out discharging, when first scraper plate arrival discharge zone carries out discharging, second scraper plate enters the ruhmkorff coil heating again, repeats above-mentioned action, finishes the continuous quenching operation.
The data that scraper plate records after quenching, this data fit relevant art requirement/standard.
Claims (2)
1. a mining scraper plate heat treating method is characterized in that, comprises the steps: scraper plate is placed on the travelling belt of scraper plate quenching machine, be heated to 880 ℃-920 ℃ after arriving the ruhmkorff coil district, arrive the water spray district then, water spray makes the workpiece quick cooling, arrives discharge zone then and unloads and get final product.
2. mining scraper plate heat treating method as claimed in claim 1 is characterized in that: its middle scraper translational speed is 0.04-0.05m/s, and be 180-240 second heat-up time, and be 60-70 second cooling time.
