Description

Technical Field

[0001] This utility model relates to the field of low-carbon ferrochrome smelting technology, and in particular to a batching device for low-carbon ferrochrome smelting. Background Technology

[0002] Ferrochrome is a ferroalloy with chromium and iron as its main components. It is one of the main alloying agents used in the steel industry. In addition to the main components of chromium and iron, it also contains impurities such as carbon, silicon, sulfur, and phosphorus. Ferrochrome contains 55% to 75% chromium and is classified into high-carbon, medium-carbon, low-carbon, and micro-carbon ferrochrome according to its carbon content. Low-carbon ferrochrome contains 0.15% to 0.50% carbon. It is mainly produced by electric furnace smelting. The main raw materials include coke, steel scrap, and quartz. When smelting low-carbon ferrochrome, batching is required. Traditional raw material proportioning devices cannot accurately weigh the raw materials, resulting in inaccurate raw material proportions. Moreover, the material tends to stick to the inside of the feeding pipe during feeding, affecting accuracy.

[0003] Patent publication number 202123211978.7 discloses a batching device for medium-carbon ferrochrome smelting, including a mixing component and a weighing and proportioning component. The mixing component includes a box, a motor, an auger core, a first discharge pipe, and a connecting plate. A weighing and proportioning component is installed on one side of the mixing component. The weighing and proportioning component includes a base plate, a weighbridge, a first plate, a second plate, a square plate, and a funnel-shaped plate. The proportion of raw material weight is input through a control panel operated by the operator. The controller controls a solenoid valve to open, transporting the raw material in a channel to the box through the second discharge pipe. When the weighbridge detects the overall weight drop of the square plate as the taken-out value, a solenoid valve is closed. The opening of other solenoid valves is done in a similar manner. This device accurately weighs and proportions the raw materials for medium-carbon ferrochrome smelting, improving the proportioning accuracy of medium-carbon ferrochrome smelting production. However, the auger is too long, and debris is easily left in the pipe and on the inner wall of the hopper, affecting the accuracy.

[0004] Therefore, those skilled in the art have provided a batching device for low-carbon ferrochrome smelting to solve the problems mentioned in the background art. Utility Model Content
