Problems solved by technology

[0002] At present, the ladles used in large, medium and small iron factories in my country only have refractory bricks in the iron ladle. After a period of use, the refractory bricks in the iron ladle will be covered with molten iron slag, making the ladle unusable. Only after the refractory bricks in the iron ladle are smashed, and then a layer of refractory bricks can be used again, the production cost increases and the energy consumption is large.

Embodiment 1

[0015] Take 45kg of high-alumina cement and 55kg of commercially available castables, and mix the above two materials to make refractory material 3. According to the percentage by weight, refractory material: water-2:1 is made into slurry, and the crushed size of refractory bricks is: 0.3-0.5cm, directly wipe the prepared oar material on the refractory brick 2 in the round bottom or flat bottom iron ladle 1.

Embodiment 2

[0017] Take 40kg of alumina cement, 60kg of ordinary refractory brick or high-alumina brick crushed material, mix the above two materials to make refractory material 3, and prepare refractory material: water-2:1 according to weight percentage to prepare slurry for later use , refractory brick crushing particle size: 0.3-0.5cm, calculated by weight percentage, according to lead powder: phosphorus tablet: black clay: water = 1: 1-2: 1-2: 0.5-1.5 The above three materials are mixed to make Paint 4 for standby;

[0018] The prepared refractory material 3 is directly wiped on the refractory brick 2 in the round bottom or flat bottom iron ladle 1, and then a layer of paint 4 is applied to the slurry.

Embodiment 3

[0020] Take 25kg of high-alumina cement, 75kg of ordinary refractory brick or high-alumina brick crushed material, and mix the above two materials to make a refractory material 3. According to the weight percentage, refractory material: water-2:1 is made into a slurry for use , refractory brick crushing particle size: 0.3-0.5cm, calculated by weight percentage, according to lead powder: phosphorus tablet: black clay: water = 1: 1-2: 1-2: 0.5-1.5 The above three materials are mixed to make Paint 4 for standby;

[0021] Put the prepared refractory material 3 slurry directly on the refractory brick 2 in the round bottom or flat bottom iron ladle 1, then apply a layer of coating 4 on the slurry, and then apply another layer on the coating 4 to have a better slurry effect. good.

Abstract

The invention relates to a foundry ladle and belongs to the field of steel smelting. The foundry ladle is characterized in that a layer of a refractory material is coated on a firebrick. The firebrick consists of the following materials by weight percentage: 20 to 50 percent of refractory cement and 55 to 85 percent of a casting material. Paint is coated on the refractory material; and the paint is counted according to weight percentage: the ratio of ceruse to phosphor sheet to black clay is equal to 1 : 1-2 : 1-2. As the refractory material is coated on the firebrick, when the firebrick in the foundry ladle is fully stuck with scoria, the foundry ladle is cooled; the scoria adhered to the refractory material is poured out; the firebrick is coated with the refractory material and can be continuously used; if a layer of the paint is coated on the refractory material, the effect is better; and if a layer of the refractory material is coated on the paint, the effect is better. The foundry ladle reduces production cost and energy consumption and prolongs the service life.

Description

1. Technical field [0001] The invention relates to a ladle and belongs to the field of iron and steel smelting. 2. Background technology [0002] At present, the ladles used in large, medium and small iron factories in my country only have refractory bricks in the iron ladle. After a period of use, the refractory bricks in the iron ladle will be covered with molten iron slag, making the ladle unusable. Only after the refractory brick in the iron ladle is smashed, can it continue to be used after a new layer of refractory brick has been penetrated, resulting in increased production costs and large energy consumption. 3. Contents of the invention [0003] The object of the present invention is to provide a ladle with low production cost, long service life and reduced energy consumption. [0004] Technical solution: The present invention includes: iron cladding, refractory bricks, and a layer of refractory material on the refractory bricks. [0005] Spray a coat of paint on ...
