Problems solved by technology
Depending on the capacity of the rotary kiln, a production cycle takes 100 to 210 minutes. If it cannot work at full capacity, the thermal efficiency will decrease and the production cost will increase.
Therefore, such a work system is more suitable for large-scale production, and the molten iron can be used up quickly. If it is used for the production of small pieces or the molding capacity is insufficient, it is not conducive to giving full play to the advantages of the rotary furnace; The main body is in different positions, and the auxiliary time accounts for about 40%, of which only feeding takes 10-25 minutes, and the production efficiency is low

Embodiment Construction
[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0036] A gas-fired rotary smelting furnace that can continuously feed materials. The structure of the main part is shown in the accompanying drawings. figure 1 The direction shown is for illustration, including preheating bin 3, main furnace 2 and burner 1. The preheating bin is connected to the main furnace, and the main furnace is equipped with burners. The raw material 12 enters the preheating bin through the conveyor belt and the hopper for Preheat, then enter the main furnace, and be heated and smelted by the burner;
[0037] The burner in this embodiment is a pure oxygen burner, which is externally connected with an oxygen and natural gas supply system and a control system. Peripheral equipmen...

The invention relates to a gas-fired rotary smelting furnace capable of continuous feeding and a production method thereof. There are two sets of rollers installed at intervals, and the axis of the main furnace is erected obliquely on the two sets of rollers. A rotating ring is fixed outside the main furnace corresponding to the support position of the rollers. The rotating ring cooperates with the rollers. The higher end of the main furnace The feed port of the main furnace is coaxially connected to the discharge port of the preheating silo; a silo support is supported at the lower end of the preheating silo, and two sets of rollers are installed between the silo support and the preheating silo. The roller is driven by a frequency conversion motor to drive the preheating bin to rotate. The cold material in the present invention is fed into the preheating bin through a structure such as a belt feeder, and is heated and preheated by high-temperature furnace gas to reduce energy consumption. The structure is simple and the operation is convenient, and the main furnace can heat up while feeding. Melting, improving production efficiency.
Description
technical field [0001] The invention belongs to the field of cast iron, in particular to a gas-fired rotary smelting furnace capable of continuous feeding and a production method thereof. Background technique [0002] Cast iron smelting furnaces can be divided into three types according to the heating method: coke cupola, electric furnace and gas furnace. The gas furnace is divided into gas cupola and converter. The gas cupola uses water-cooled grille, which has potential safety hazards. The temperature of molten iron is low, and it can only be used in conjunction with an electric furnace to maximize its benefits. [0003] At present, the rotary furnaces in use are all intermittent working systems, with a thermal efficiency of about 50%. The entire working cycle is divided into five different stages: feeding, melting, overheating, tapping liquid, and slag tapping. Depending on the capacity of the rotary kiln, a production cycle takes 100 to 210 minutes. If it cannot work at...
