Problems solved by technology

[0002] Every year, large steel mills produce a large amount of scrap steel slag. In order to avoid these scrap steel slags from polluting the environment, they are usually landfilled, resulting in a huge waste of resources. How to use these scrap steel slags to realize resource recycling has become a concern of people.
So some people wash the ship with scrap steel slag, but it still fails to realize the full utilization of waste resources

Embodiment 1

[0019] The production method for producing 20 kg heavy elevator counterweights adopts steel scrap slag with an iron content of 30%, iron plates with a thickness of 0.80 mm and cement as raw materials, including the following processes:

[0020] 1. Make the counterweight metal shell: make the iron plate with a weight of 8.5% of the finished counterweight and a thickness of 0.80mm to make a metal shell consisting of an iron plate container and a cover. The iron plate container has an opening on the top and a cover It matches the iron plate container, the size of the metal shell is consistent with the size of the required counterweight, and the iron plate container and its cover are treated with antirust;

[0021] 2. Scrap steel slag treatment: the scrap steel slag with an iron content of 30% is crushed first, and then passed through a pulverizer to make the particle diameter less than 3mm;

[0022] 3. Mixing material: get 17.202 kilograms of steel scrap slag processed in step 2,...

Embodiment 2

[0026] Using waste steel slag with an iron content of 40%, iron plates with a thickness of 0.80 mm and cement as raw materials, including the following processes:

[0027] 1. Make the counterweight metal shell: make the iron plate with a weight of 8.5% of the finished counterweight and a thickness of 0.80mm to make a metal shell consisting of an iron plate container and a cover. The iron plate container has an opening on the top and a cover It matches the iron plate container, the size of the metal shell is consistent with the size of the required counterweight, and the iron plate container and its cover are treated with antirust;

[0028] 2. Scrap steel slag treatment: the scrap steel slag with an iron content of 40% is crushed first, and then passed through a pulverizer to make the particle diameter less than 3mm;

[0029] 3. Mixing material: get 16.47 kilograms of steel scrap slag processed in step 2, 1.83 kilograms of cement, and 0.915 kilograms of water (water will volati...

Abstract

The invention discloses a method for forming elevator counterweight blocks by waste steel slag, which uses the waste steel slag with the iron content of 30 percent to 40 percent, iron plates with the thickness of 0.78mm to 0.82mm and cement as raw materials. The method comprises the following processes: 1. preparing a metal shell of the counterweight block; 2. processing the waste steel slag: the waste steel slag is crushed and passes through a powdering machine to lead particle diameters to be less than 3mm; 3. mixing materials: the raw materials are weighed according to the following weight radio: the waste steel slag: 90 percent to 94 percent, the cement: 6 percent to 10 percent, water: 5 percent to 6 percent, the mixture material is prepared after being mixed evenly and fully by a mixer; 4. molding: the mixture material is transmitted to a pressure machine by a transmission belt to be pressed into needed modules automatically, and then the needed modules are transmitted to an iron plate container made by the step 1 by the transmission belt; 5. maintaining: the modules are maintained for 6 to 8 days, and an upper cover is covered and welded after the counterweight block is hardened completely, and then the finished product is obtained. The method for forming the elevator counterweight blocks by the waste steel slag has the advantages that the waste can be turned into useful materials, thus conforming to the national requirements of building a resource-conserving society.

Description

technical field [0001] The invention relates to a method for utilizing scrap steel slag, and more specifically relates to a method for using scrap steel slag to form elevator counterweights. Background technique [0002] Every year, large steel mills produce a large amount of scrap steel slag. In order to avoid these scrap steel slags from polluting the environment, they are usually landfilled, resulting in a huge waste of resources. How to use these scrap steel slags to realize resource recycling has become a concern of people. . So some people use scrap steel slag to wash the ship, but it still fails to realize the full utilization of waste resources. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a method for forming elevator counterweights by using scrap steel slag, to realize turning waste into treasure, to protect the environment, and to make elevator counterweights better than any...
