Abstract

A wear-resistant scraping plate of vertical grinding machine comprises a mother scraping plate body, a wear-resistant layer, and a cemented carbide layer. A cemented carbide layer is overlaid on the surface of a wear-resistant layer which is first overlaid on the mother scraping plate body, with the results of greatly-increased wear resistance of the scraping plate, prolonged service life, reduced manufacture cost, easy overhaul and replacement and reduced labor intensity. In addition the accumulated materials in the scraping material chamber can be timely expelled resulting in well ventilation in the grind, load reduction of the machine and increased grinding output and stability.

Description

The wear-resisting material scraping plate of vertical mill

Technical field

The utility model relates to a kind of material scraping plate, is a kind of wear-resisting material scraping plate that is used for vertical mill specifically.

Background technology

In recent years along with the continuous expansion of industry production capacities such as building materials, coal; The import milling equipment is increasing; Vertical Mill is able to extensive use as milling apparatus preferably, especially in recent years the development of iron and steel enterprises recycling economy, seek new growth engines, establish the slag milling production line one after another; That carries out blast furnace slag utilizes engineering again, more makes Vertical Mill use and obtains unprecedented development.Yet for the difficulty mill material that with the slag is typical case's representative; No matter be production capacity or grinding effect; Homemade Vertical Mill far can not satisfy production requirement, thereby present large-scale Vertical Mill still depends on import, thereby causes equipment and parts procurement expensive thereof; And delivery cycle is tediously long, all brings unfavorable factor for the production and the performance of enterprises.

It is nearly 1/2nd that the every running of material scraping plate 3～4 months under the mill of vertical mill at present, material scraping plate will be ground off, owing to diminish after the material scraping plate wearing and tearing; The buildup of scraping in the material chamber can not in time be discharged from; Not only cause main current of electric rising, mill load increase, output can not to add, but also influence mill inner ventilation, cause hot blast skewness in mill; Make the mill grinding pressure have the unbalance loading phenomenon, this also is to cause one of high reason of Vertical Mill thrust bearing shoe valve pressure.Therefore, press for a kind of low cost of development, ultra wear-resisting vertical mill material scraping plate.

Summary of the invention

The utility model is exactly a kind of Vertical Mill material scraping plate that provides in order to solve the problems of the technologies described above, and purpose is in order to prolong material scraping plate service life, to reduce manufacturing cost; Easy access is changed; Reduce labor strength, make simultaneously to scrape and expect that buildup can in time be discharged from the chamber, mill inner ventilation is normal; Mill load reduces, and improves Vertical Mill output and stability.

The utility model solves the technical scheme that its technical problem adopted: the wear-resisting material scraping plate of a kind of vertical mill; Form by parent scraper plate, wearing layer, hard alloy layer; Elder generation's built-up welding one deck wearing layer on the parent scraper plate; Then at wearing layer surface overlaying one deck hard alloy layer, thereby increase substantially the wearability of material scraping plate.

The beneficial effect of the utility model is, prolonged material scraping plate service life, low cost of manufacture; Easy access is changed, and reduces labor strength, makes simultaneously to scrape to expect that buildup can in time be discharged from the chamber; Mill inner ventilation is normal, and mill load reduces, and improves Vertical Mill output and stability.

1. parent scraper plates, 2. wearing layer, 3. hard alloy layer among the figure.

The specific embodiment

In Fig. 1, first built-up welding one deck wearing layer 2 on parent scraper plate 1 then at wearing layer 2 surface overlaying one deck hard alloy layers 3, thereby increases substantially the wearability of material scraping plate.

Claims

1. the wear-resisting material scraping plate of vertical mill is made up of parent scraper plate, wearing layer, hard alloy layer, it is characterized in that: elder generation's built-up welding one deck wearing layer on the parent scraper plate, and then at wearing layer surface overlaying one deck hard alloy layer.
