In a notification sent to the exchange by the Board of Directors of Aisha Steel Mills Limited (ASL -0.79pc), the company has started commercial operations of its Chinese Push Pull Pickling Line, German Rolling Mill and Austrian Batch Annealing Furnace
on Wednesday (June 26).
Shanghai, China, July 25, 2018 --(PR.com)-- Shanghai Shihang Copper Nickel Pipe Fitting Co., Ltd., today updated its annealing furnace
to improve physical properties of copper nickel pipes, flanges, and fittings.
The cold rolled plates were held for 600 s in an annealing furnace
which had an atmosphere mixed of [N.sub.2] and [H.sub.2] (3: 1).
Other phase-change temperature indicators include pellets (to be placed on or inside the piece--in an annealing furnace
, for example), liquids (to be painted on the piece), and labels coated with temperature-indicating material (which are affixed to a component to measure temperature exposure).
Increasing the size of the radiant tube section of the line's annealing furnace
, where the steel is given the required mechanical properties ahead of the zinc coating process, has enabled an increase in capacity of about 25% to 500,000 tonnes per year.
Typically, the dew-point required for optimum performance in an annealing furnace
is between -70 and -50 C, depending on the type of metal being treated and the end results required.
, three suites of Solidworks and two suites of ESI Quickcast to accommodate its new customers, which are bringing in increasingly large parts.
The contract encompasses the mechanical equipment, including a skin-pass mill, the complete electrical equipment, automation, and the annealing furnace
. The line is to start operations in mid-2011.
On basis of carried out scientific-technical investigations of heat conditions of the annealing furnaces
a new furnace No 10 of production capacity more than 2000 t of annealed products per month was built, which brought production to the leading position on market of electrode products; complex of works for scientific support of rules of the annealing furnace
operation were carried out; experimental campaigns were accompanied by computer monitoring of temperature fields, which made it possible to operatively trace adjustment procedure of commissioning of furnace No 10.

The galvanneal process, which forms a protective layer on steel sheet, involves dipping the steel in molten zinc followed by high-temperature treatment in an annealing furnace
. The production of uniform, high-quality galvanneal steel is possible only through strict temperature control.
