Multidirectional Parallel Tilting Mechanism for Steelmaking Rotary Converter

Abstract

A multi-directional parallel tilting mechanism for a steel making rocking converter comprises an engine base, a movable table, the rocking converter, two planar dual-drive branches of the same structure and two counterweight devices, wherein the rocking converter is fixedly connected with the movable table; the two planar dual-drive branches are parallelly and symmetrically distributed on two sides of the rocking converter left and right; the two counterweight devices are symmetrically distributed on the outer sides of the two planar dual-drive branches left and right in a co-planar manner; two ends of two RPR linear driving branches in each planar dual branch are connected with rotary pairs at the two ends of an upper cross shaft and a lower cross shaft to form a planar closed-loop dual-moving driving branched chain; and supports in the counterweight devices are fixedly connected with the engine base, pulleys are arranged at the upper ends of the supports, and the two ends of steel wire ropes are connected with the movable table and a balance weights. The multi-directional parallel tilting mechanism is simple in structure and high in bearing capacity and rigidity, and the rocking converter is large in working space and good in rocking flexibility; molten iron and alloy in the converter are uniformly mixed in a multi-directional rocking and rotating manner, and blowing is performed by an oxygen gun, so that not only can the tilting impact torque be reduced, but also the high-quality steel can be refined and the lining life is prolonged.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, and in particular relates to a tilting mechanism of a steelmaking rotary furnace. Background technique [0002] The combination of steelmaking converter and oxygen lance blowing is one of the main equipments for steelmaking at home and abroad. At present, most of the existing steelmaking converters at home and abroad use one-degree-of-freedom tilting mechanical equipment to drive the converter to tilt through the support ring. The tilting mechanical equipment is driven by multiple AC variable frequency motors, and the multiple motors are in the form of multi-point meshing full suspension, and the torque is balanced through the torsion bar device. Because this type of tilting mechanical equipment only tilts with one degree of freedom, the impact moment of the reversing tilting is very large, the mixing performance of molten iron and alloy materials in the furnace is poor, and the ability to...

Problems solved by technology

The one-degree-of-freedom tilting mechanism of the traditional steelmaking converter has a large impact moment when the tilting mechanism changes direction, the mixing performance of molten iron and alloy materials in the furnace is poor, the ability to remove (hydrogen, phosphorus, carbon, sulfur, gas) and impurities is poor, and the life of the converter lining is poor. shorter
