Re: [MW:16386] Vacuum Packed LH Electrodes

dear friend,

as per my opinion, it must be placed in site quiver at 120C because vaccum pack replaces the requirement of rebaking not holding. 

wat manufacturer is written 9 hrs.is regarding max. working time before rebaking requries.

Dear Experts, 

We are using E 7018-1 H4 Vacuum packed Electrodes for our project. ( Refer attachments ) , where manufacturer recommendations is mentioned as : 

HD [ ml/100g] : at opening time : <5 

Working time after opening : 9h at 80% RH / 27 deg C 

After this period rebaking : 2h/340-360 deg C 

Brand : Supercito VP Medium ,Oerlikon , Air Liquide Wedling France. 

Weather Condition at site : 78- 80 % Humidity , Temp 26-30 Deg C. 

My question is :

•  After opening packet at the start of the days work , is it necessary to transfer a pack of  electrodes to a portable quiver for holding at temp 100 deg C to prevent further moisture pick up ? or it is not required as manufacturer says that after opening up to 9 hrs it can be used at 80% / 27 deg C . 

• Electrodes rebaking cycle depends upon which factors? Some client specifies recycling 1 time  , some 2 times ... [ As per BIS 13851:1993 , ( R 2006) - Storage & redrying of coverd electrodes  before use recommendations- 3 times ] 

Please clarify . 

Thanks & regards.
