Steel billets prominant manufacturer

Excavators and hand drills play an important role in the construction process. The shovel is one of the oldest tools for moving soil, dating back 12,000 years. Bill is made of different materials and is marketed. The word Bill is one of the ancient words of the Persian  steel billets, which has been similar in the Pahlavi language. Bass has built an ergonomic type of shovel; By using this type of shovel, less damage will be done to the human body during drilling.

What are steel billets used for?

A scaffold is a wooden or metal structure that allows people to reach heights. In fact, with the expansion of high-rise structures, the need to access heights to build and repair buildings became more tangible. Therefore, metal pipes (black straight seam pipe called scaffold pipe) or wood were used, which are sometimes used as supports for other parts of the structure. The construction of scaffolding requires special skills because if a scaffolding collapses, the risk of casualties is very high. Therefore, the experts of Shahr-e-Ahan try to provide their audiences with generalities of scaffolding pipe, its connections and components, and, most importantly, the points that must be observed.

Manufacturing process of steel billets

Galvanized sheets are produced in two ways, hot and cold. The cold method is performed by electrolysis of zinc salts inside a water solution and is usually used for domestic purposes, but hot galvanization is the coating operation through the continuous passage of sheet metal through the zinc melt bath, which is done in two continuous methods. And is divided into non-continuous. In the following, we will examine the hot method. In general, steelmaking furnaces include non-oxide and radiant furnaces. In non-steel bars furnaces, preheating and deoxidation steps are performed from the surface of the sheet.

Carbon monoxide and hydrogen are generally produced by the incomplete combustion of methane gas in burners, as well as the burning of possible fats based on carbon and hydrogen. These gases are reductive, and as a result of direct contact with the surface of the sheet, they reduce the surface oxides to some extent. In radiant furnaces, the thermal operation of sheet annealing takes place. In this furnace, the flame is not in direct contact with the sheet and is inside the tube and the heat is transferred to the sheet as radiation. The atmosphere in this furnace is nitrogen and hydrogen gases. After oxidation and achieving the desired mechanical properties, the sheet temperature reaches the appropriate temperature for entering the molten round steel billet, which is about 460. C. The sheet then enters the molten bath and comes out of the molten bath with the molten zinc surface.
