Efficient Steel Rolling Mill Machinery With Low Power Consumption

High Durability Rolling Mill Furnace Fine Finish With No Whistling Noise

Description of Rolling furnace

Rolling furnace is also known as: steel billet soaking furnace, billet rolling furnace, billet preheating furnace, billet forging furnace, billet baking furnace, billet continuous rolling furnace, etc. It mainly acts on: steel billet after steel melting heat / heat-transmission operation automatically rolls off and slides out when the temperature reaches the preheating rolling requirement, and directly enters the hot-rolling unit by the roller conveyor mechanism, and passes through a series of operations such as continuous rolling to meet the production requirements. IGBT induction heating equipment has been used for more than 20 years, and it has launched innovative products for the first time in China. The energy-saving medium frequency steel rolling furnace introduced this time is a major technological innovation. It has fundamentally revolutionized the old-fashioned intermediate frequency featuring thyristors and is an innovative replacement for the old-fashioned KGPS IF.

Technical characteristics

Main features: IGBT devices, global procurement of components, high-efficiency combined resonance technology, low-inductance circuit arrangement, large-scale word circuit, and more comprehensive and mature protection technology.

Three advantages

1, a substantial power saving, each heating a ton of steel, power consumption of 380 degrees.

2, will not bring network side pollution, power supply transformers do not heat, substation compensation capacitors do not heat, do not interfere with other equipment work.

3. Reduce the capacity of the power supply transformer.

4. Match the relevant transmission mechanism.

Selection basis

(1) Select power according to output and production beat

WJZ-200: heating output per hour: 500kg;

WJZ-300: heating output per hour: 750kg;

WJZ-500: heating output per hour: 1250kg;

WJZ-750: heating output per hour: 1500kg;

WJZ-800: heating output per hour: 2000kg;

WJZ-1000: heating output per hour: 2200kg;

WJZ-1500: heating output per hour: 3500kg;

WJZ-2000: heating output per hour: 4000kg;

Production beat (number of heating per minute) = hourly output / workpiece weight.

(2) Select the frequency according to the size of the workpiece

The recommended frequency of the workpiece with diameter Φ20～Φ40mm is 4KHz; the recommended frequency of workpiece with diameter Φ40～Φ60mm is 3KHZ; the recommended frequency of workpiece with diameter Φ60～Φ100mm is 1KHZ～2KHZ;

The 60*60 or 80*80mm billet is recommended to use the intermediate frequency 6KHZ frequency; the 100*100 or 120*120mm is recommended to use the intermediate frequency 3KHZ. More detailed parameters about the frequency can be determined according to the workpiece.

Furnace size matching:

The intermediate frequency heating furnace or the intermediate frequency preheating furnace is mainly matched with the inductance of the power cabinet. Generally, it is customized by thick-walled flat copper tubes or square tubes and round tubes. The number of turns and the width and thickness of the windings mainly include workpieces. The size of the shape is customized, and the overall width of the furnace is customized by the production cycle of the next process. The selection of the inductance is based on the oscilloscope, and it is better to wait for the power cabinet to reach the optimal state.

Parameters Table:

Application range:

1. Round steel, bar, steel pipe, steel wire, etc.

2. Bar, pipe, steel billet, steel bar, etc.

3. Preheating and heating of oil pipelines, steel bars and round steel

4. Pipeline, bar, wire and other online modulation processing

5. Matching production line customized heating process and heating operation

Power saving effect

IGBT intermediate frequency power saving effect:

Take WJZ-400 as an example: class 10 tons of forgings, 80-100 degrees per ton of electricity, 560-700 yuan for electricity saving in class; 20,000 yuan for electricity saving in the month; double or three shifts, monthly electricity saving 4 10,000-60 million yuan. Equipment investment can be recovered in a few months.

Package delivery:

The whole type is custom-formed by high-temperature baking compression template, and the side is supported by angle iron frame to ensure the reliability of the arrival of the goods; the matching packing list before shipment from the factory: equipment installation and maintenance instructions; equipment inspection certificate; warranty card.

Pledge

1. The seller installs and debugs the site and trains the buyer.

2. Implement (1+1) technical after-sales service for users, that is, one equipment has a full-time engineer to carry out perennial technology tracking service after leaving the factory.

3. In the event of a malfunction, the seller guarantees that it will arrive at the buyer's site within 24 hours after receiving the buyer's notice.

4. The warranty period is 12 months. During the warranty period, non-human equipment quality problems cause damage to equipment and components, and the seller performs maintenance free of charge.

5, in addition to the warranty period, provide lifelong paid repair and maintenance services.
