Preparation method of efficient multi-planar cylindrical steel forging

Abstract

The invention relates to a preparation method of an efficient multi-planar cylindrical steel forging and belongs to the technical field of smelting and casting production of metal steel balls. According to the efficient multi-planar cylindrical steel forging, pig iron, waste steel and alloys are selected as raw materials, melted by an intermediate frequency furnace and smelted to form high-quality molten steel, a cylindrical steel forging box type steel mold is used for casting production, a product is naturally cooled, quenched by an electric heating furnace, subjected to finish forging forming and trimming, and the efficient multi-planar cylindrical steel forging is obtained. According to the efficient multi-planar cylindrical steel forging, the cylindrical steel forging box type steel mold is used for casting production, and singleness of cast products is improved; the safety of the cylindrical steel forging box type steel mold is high, molten iron is cast through a casting riser, the condition that the molten iron is splashed easily and injures people is prevented, the work injury accident is reduced, and safety production management is facilitated; by comparison with ordinary casting, the injury accident due to molten iron splashing is fundamentally prevented; the steel forging is remarkably superior to a steel ball in grinding when used for ore grinding in a mine and a machining enterprise, and the grinding cost of the mine and the machining enterprise is greatly saved.

Description

technical field [0001] The invention relates to a method for preparing high-efficiency multi-plane cylindrical steel forging, and belongs to the technical field of metal steel ball smelting and casting production. Background technique [0002] Casting is to inject molten metal into a hollow mold made of high-temperature-resistant materials, and then condense to obtain a product of the expected shape. It is an earlier metal thermal processing technology mastered by humans, with a history of about 6,000 years. In 3200 BC, copper frog castings appeared in Mesopotamia; between the 13th and 10th centuries BC, China had entered the heyday of bronze castings, and the craftsmanship had reached a very high level, such as the heavy The 875-kilogram Simuwufang Ding, the Zenghou Yizun plate of the Warring States Period, and the light-transmitting mirror of the Western Han Dynasty are all representative products of ancient casting. The early casting was greatly influenced by pottery, and...

Problems solved by technology

The concentration of the foundry industry is low, and the production process is generally carried out in stages, resulting in a large amount of waste of resources and energy. The overall competitiveness of the market is not strong, and opportunities and challenges for the development of foundry products coexist simultaneously.
