Embodiment 1

[0084] The powder spraying system of this embodiment is applied to a scrap steel continuous preheating electric arc furnace, and is provided with 3 powder spraying working points (dusting working points A, B, C), and the maximum powder consumption is 2000kg / furnace.

[0085] powder spraying system (such as Figure 6 Shown) includes 2 storage modules (storage modules A, B), 2 delivery modules (delivery modules A, B), and 3 powder spraying modules (powder spraying modules A, B, C). Distributed layout design is carried out according to the process requirements. The material storage module is located 100 meters away from the powder spraying point of the furnace. The powder spray module is located near the electric arc furnace on the electric arc furnace platform. The sending device of each material storage module communicates with each The powder conveying main pipeline of each conveying module is connected, and a valve is set on the pipeline between the sending device and the pow...

Abstract

The invention relates to a distributed powder spraying system and method, belongs to the technical field of powder spraying metallurgy, and solves the problems that an existing powder spraying system is small in powder storage amount, frequent in powder filling and low in production efficiency. Comprising a feeding working area, a conveying working area, a powder spraying working area and a gas control unit. The feeding working area comprises at least one storage module, the conveying working area comprises at least one conveying module, and the powder spraying working area comprises at least one powder spraying module; the number of the storage module, the conveying module and the powder spraying module is not one. Each material storage module is connected with at least one conveying module, each powder spraying module is connected with at least one conveying module, the gas control unit is communicated with the material storage modules, the conveying modules and the powder spraying modules, and the gas control unit provides gas for conveying powder for the material storage modules, the conveying modules and the powder spraying modules; a valve is arranged between the storage module and the conveying module, and a valve is arranged between the powder spraying module and the conveying module. The powder storage amount is increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of powder spraying metallurgy, in particular to a distributed powder spraying system and method. Background technique [0002] Powder spraying metallurgy is an important metallurgical technology with a wide range of applications.
