[0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces to the rolling and forging temperature. Heating furnaces are used in many industries such as petroleum, chemical, metallurgy, machinery, and building materials. At present, when heating furnaces are in use, iron chips, residues, and dust particles are attached to the surface of the steel. During heating, the dust and iron chips will fall off and form iron oxide scale on the inner wall of the heating furnace body. The accumulation of iron oxide scale can easily affect the later use of the heating furnace.

However, in actual use, the iron sheet has a strong adhesion and requires a lot of force to scrape it. The scraping method only provides the up and down movement of the first scraper and the second scraper, and the scraping effect on the iron sheet is general. In addition, the cylinder is arranged inside the heating furnace, which is easily damaged by high temperature, resulting in a reduced service life and low practicality. Now there is an urgent need for a slag scraping mechanism at the end of a steel rolling heating furnace to solve the above-mentioned problems. Utility Model Content
