[0020] Example 1
[0021] Take 55% by mass of magnesite tailings and 45% by mass of iron ore powder. Mix the two materials and dry them at a temperature of 110°C. The dried material is ball milled in a ball mill, and the ball milled raw materials are in a mixer Add 5% by mass water for mixing, and press the mixed material into a blank with a force of 500KN. The billet was dried at 110°C for 24 hours, and the dried billet was heated in a furnace to 650°C for 30 minutes, kept at 850°C for 30 minutes, and 1500°C for 120 minutes to form aggregates. The aggregate crushing screen is divided into 5-3mm; 3-1mm; 1-0.088mm; 0.088-0.02mm, according to the mass percentage of 5-3mm particle size 20%; 3-1mm particle size 30%; 1-0.088mm particle size 15%; 0.088-0.02mm particle size 35% proportion, while adding 5% by mass of sulfite pulp waste liquid as a binder, then adding 1% of the aggregate mass of steel fiber to mix evenly, and mix with a mixer . After uniform mixing, the heat storage br...

[0022] Example 2
[0023] Take 40% mass percentage of magnesite tailings and 60% mass percentage of iron ore powder. Mix the two materials and dry them at a temperature of 110°C. The mixed materials are ball milled in a ball mill, and the ball milled raw materials are milled in a mixer. Add 5% by mass of water for mixing, and press the mixed material into a blank with a force of 550KN. The billet was dried at 110°C for 24 hours, and the dried billet was heated in a furnace to 650°C for 30 minutes, kept at 850°C for 30 minutes, and 1500°C for 120 minutes to form aggregates. The aggregate crushing screen is divided into 5-3mm; 3-1mm; 1-0.088mm; 0.088-0.02mm particle size, according to the mass percentage 5-3mm particle size 20%; 3-1mm particle size 30%; 1-0.088mm Particle size 20%; 0.088-0.02mm 30% particle size proportioning, while adding 5% by mass of sulfite pulp waste liquid as a binder, and then adding 1.5% of the aggregate mass of steel fiber to mix evenly, and mix with a mi...

[0025] Take 65% by mass of magnesite tailings and 35% by mass of iron ore powder. Mix the two materials and dry them at a temperature of 110°C. The dried material is ball milled in a ball mill, and the ball milled raw materials are in a mixer Add 5% by mass of water for mixing, and press the mixed material into a blank with a force of 500KN. The billet was dried at 110°C for 24 hours. The dried billet was heated in a furnace to 650°C for 30 minutes, kept at 850°C for 30 minutes, and 1500°C for 120 minutes to form aggregates. The aggregate crushing screen is divided into 5-3mm; 3-1mm; 1-0.088mm; 0.088-0.02mm, according to the mass percentage 5-3mm particle size 23%; 3-1mm particle size 30%; 1-0.088mm particle size 15%; 0.088-0.02mm, 32% particle size ratio, while adding 5% by mass of sulfite pulp waste liquid as a binder, and then adding 1.3% of the aggregate mass of steel fiber to mix uniformly, and mix with a mixer . After being uniformly mixed, the heat st...
