preparation example Construction

[0023] According to the present invention, the preparation method of the rare earth alloy steel plate may include the following steps:

[0024] (1) Metal material smelting: Pretreatment of molten iron is followed by converter smelting and deoxidation alloying. Among them, the composition of outbound molten steel controlled by converter smelting and deoxidation alloying includes: C, Si, Mn, Mo, Cr, P and S , and based on the total weight of the molten steel, P≤0.03% by weight and S≤0.02% by weight; the temperature of the outbound molten steel for converter smelting and deoxidation alloying is 1500-1540°C;

[0025] (2) Microalloying treatment: Refining the outbound molten steel obtained in step (1) in an LF furnace; the temperature of the outbound molten steel in the LF furnace is 1520-1560°C;

[0026] Wherein, through the joint control of step (1) and step (2), the molten steel out of the LF furnace contains: 0.1-1% by weight of C, 0.4-0.7% by weight of Si, 0.4-0.65% by weight ...

[0041] This preparation example is used to illustrate the preparation method of the rare earth alloy steel plate provided by the present invention

[0042] (1) Metal material smelting: the molten iron and steel scrap after desulfurization pretreatment are used for converter smelting, and the sulfur content in the molten iron entering the furnace is controlled to be ≤0.02% by weight. In the early stage of blowing, slag is dissolved early, lime is added in an amount of 50-70kg per ton of steel, and slag-making ore is added in an amount of 12-20kg. After the molten steel is completely melted, ferromanganese, ferrosilicon and ferromolybdenum are added, and after complete deoxidation Tapping: Controlled converter smelting and deoxidation alloying outbound molten steel components include: C, Si, Mn, Mo, Cr, P and S, and based on the total weight of molten steel, P≤0.03% by weight and S≤ 0.02% by weight; the outbound molten steel temperature for converter smelting and deoxidation all...

Abstract

The invention relates to the field of ship loader, and discloses a ship loader chute tube throwing elbow, a ship loader chute tube and a ship loader. A lining plate (2) is arranged on a material receiving surface of the ship loader chute tube throwing elbow (1), and is a rare earth alloy steel plate. The ship loader chute tube throwing elbow adopts the rare earth alloy steel plate as the lining plate, can effectively improve the wear resistance, the impact resistance and the reliability, prolongs the service life of the lining plate, improves the ship loading operation efficiency, and saves the equipment maintenance cost.

Description

technical field [0001] The invention relates to the field of ship loaders, in particular to a ship loader chute throwing elbow, a ship loader chute and a ship loader. Background technique [0002] The ship loader is a large-scale machine used for loading ships at the bulk terminal. The general ship loader is composed of a cantilever belt conveyor, a transition belt conveyor, a ship loader (telescopic) chute, a tail car, a running device, a gantry, a tower, a pitching device, a slewing device and a throwing elbow. [0003] During the process of the ship loader loading coal onto the cargo ship, the coal falls on the throwing elbow through the ship loader chute, and the coal falling direction is changed through the throwing elbow to realize the unwinding operation. The throwing elbow of the shiploader chute is the last hurdle in the loading process, and the lining of the throwing elbow is the lining plate with the worst operating conditions in the loading port and the most pro...
