There are several different types of steel billet reheating furnaces used in the metal industry. These furnaces are designed to heat steel billets to a specific temperature before they are further processed or shaped into various end products. The main types of steel billet reheating furnaces include:
1. Pusher Type Furnace: This type of furnace uses a pusher mechanism to move the billets through the furnace. The billets are loaded onto a roller conveyor and pushed into the furnace using mechanical pusher plates. As the billets move through the furnace, they are heated by the combustion gases or electrical heating elements.
2. Walking Beam Furnace: In a walking beam furnace, the billets are placed on a series of moving beams or skids. These beams move in a continuous loop, carrying the billets through the furnace. As the billets move, they are heated by the burners or electrical heating elements located above and below the beams.
3. Rotary Hearth Furnace: This type of furnace consists of a rotating hearth on which the billets are placed. The hearth rotates, bringing the billets through different temperature zones within the furnace. The billets are heated by the burners or electrical heating elements located above the hearth.
4. Continuous Furnace: A continuous furnace is a type of furnace where the billets are continuously fed into one end and discharged from the other end. The billets move through the furnace on a conveyor belt or roller conveyor, being heated by the combustion gases or electrical heating elements as they pass through.
5. Walking Hearth Furnace: In a walking hearth furnace, the billets are placed on a hearth that moves in a reciprocating motion. The hearth moves back and forth, bringing the billets through the furnace. The billets are heated by the burners or electrical heating elements located above and below the hearth.
Each type of steel billet reheating furnace has its own advantages and is suitable for specific applications. The choice of furnace depends on factors such as the required heating capacity, the size and shape of the billets, the desired temperature profile, and the energy efficiency requirements.
There are several types of steel billet reheating furnaces, including walking beam furnaces, pusher furnaces, rotary hearth furnaces, and roller hearth furnaces. Each type has its own advantages and uses, depending on the specific requirements of the steel production process.
