Detailed Description
The invention relates to a coke oven masonry process for building a coke oven masonry by using a robot, which comprises the following steps:
laying refractory bricks forming the coke oven masonry by using an industrial robot;
the refractory bricks of each layer and the refractory bricks of each layer are connected by textile products or fiber products which are soaked or coated with refractory slurry/refractory mortar.
The textile or fiber product is impregnated or coated with a refractory mortar/cement paste in situ prior to use.
The textile or fiber product is a preform infiltrated or coated with a refractory mortar/cement.
The textile or fiber product impregnated or coated with the refractory mortar/cement is cut and laid by an industrial robot.
The textile product is a fire-resistant textile product, and the fiber product is a fire-resistant fiber product.
Before laying the refractory bricks, a layer of refractory mortar/refractory mortar with the thickness of 0.1-5.0 mm is coated or sprayed on the contact surface of the refractory bricks and a textile product or a fiber product in advance.
When the industrial robot lays refractory bricks forming the coke oven masonry, the refractory bricks manufactured according to the coke oven masonry structure in advance are placed at preset corresponding placement positions.
And after the industrial robot lays each layer of coke oven brickwork, performing pointing treatment on the gaps on the surface of the brickwork.
The seam comprises a horizontal seam and a vertical seam.
After the industrial robot lays a layer of refractory bricks, cleaning the expansion joint of the furnace wall and laying an expansion joint filling material, wherein the upper part of the expansion joint is protectively sealed or a sliding layer is laid by the industrial robot.
The function of textile or fiber products (hereinafter referred to as refractory products) soaked or coated with refractory mortar/refractory mortar in the structure of the coke oven body can be summarized as follows:
1. filling; the filling material is filled between the refractory bricks, so that a wall body formed by the refractory bricks is tight, and gas is prevented from leaking between the coke oven structures;
2. bonding; connected between the refractory bricks to form a whole to resist the lateral pressure on the brick wall.
At low temperature parts, the refractory product mainly plays a filling role, and the brick joints among the refractory bricks can be considered to be reduced; at high temperature, the refractory product plays a role of filling and bonding at the same time, and at the moment, the refractory product is partially sintered and bonded with the refractory bricks, or is bonded with the refractory bricks together with refractory mortar or softened refractory mortar.
The invention adopts textile products or fiber products soaked or coated with refractory mortar/refractory mortar to replace the traditional refractory mortar and fill the refractory mortar between refractory bricks, thereby avoiding masonry errors and construction defects caused by operations of coating, brick kneading and the like in mortar preparation and construction. The refractory bricks and the refractory products can be prefabricated into finished products and can be stored for a long time, and the characteristics provide possibility for automatically building the coke oven body by adopting an industrial robot (an artificial intelligent robot). The prefabricated fire-resistant product can be sealed by upper and lower layers of plastics, and is rolled up and stored in a sealed barrel, so that the fire-resistant product is convenient to store, transport and cut on site.
The existing industrial robot can completely complete the operation processes of sequentially selecting refractory bricks, cutting refractory products, finishing the masonry process, pointing, finishing the surface of a wall body and the like according to the program. Laying refractory bricks of the coke oven masonry by using an industrial robot, selecting the refractory bricks, laying the refractory bricks according to a preset placing position, connecting each layer of refractory bricks or the refractory bricks on the same layer by using a special refractory product, and cutting and laying the refractory product by using the industrial robot; after the industrial robot lays a layer of refractory brick masonry, the surface of the masonry is cleaned, and a gap on the surface is subjected to pointing treatment.
According to the construction requirement, a layer of refractory slurry or refractory mortar can be coated or sprayed on the contact surface of the refractory brick and the refractory product in advance; this step may be omitted depending on the bonding of the refractory bricks to the refractory article.
Cleaning an expansion joint of the furnace wall after the industrial robot lays a complete layer of bricks, and paving an expansion joint filling material, wherein the upper part of the expansion joint is protectively sealed or a sliding layer is paved by the industrial robot; the whole coke oven body building process does not need a brick kneading process and is completely finished by a robot.
